Airwars Investigation Sheds New Light on
Human Cost of the Washington’s ‘War on Terror’
Oscar Rickett / Middle East Eye
(September 6, 2021) — As many as 48,000 civilians have been killed in the last 20 years as a direct result of US air strikes, according to an Airwars investigation that sheds new light on the human cost of Washington’s so-called “war on terror”.
Publishing its findings ahead of the 20th anniversary of the 9/11 attacks, the UK-based monitoring group concluded that at least 22,679, and potentially as many as 48,308 civilians, were killed by US aerial strikes between 2001 and 2020.
Using local sources and official US military data, Airwars concluded that, in the years following the 9/11 attacks, the US has carried out a minimum of 91,340 air strikes across seven major conflict zones.
Air strikes were carried out by the US military in Iraq, Syria, Afghanistan, Somalia, Yemen, Pakistan and Libya. The heaviest casualties were in Iraq and Syria. Between 11,474 and 24,136 civilians were killed in Iraq from 2001 to 2020, while in Syria as many as 15,573 were killed in US air strikes.
In Afghanistan, Airwars found that as many as 6,799 civilians were killed, while in Yemen that figure is 412, in Somalia 333, in Pakistan 969 and in Libya 86.
“For much of the last 20 years people living in Washington or New York could have been forgiven for forgetting their country was at war. Whether a drone strike in a Yemeni village or a military base in rural Afghanistan, it often felt far removed – almost another world – but that isn’t how it felt for those millions of people living in those conflicts,” Joe Dyke, senior investigator at Airwars, told Middle East Eye.
“This isn’t all Airwars data – in fact, we relied upon the work of many other conflict monitoring organisations – but by bringing it together we hoped to lay out the real human toll of 20 years of the ‘forever wars.'”
In addition to US military and other internationally produced data, a range of local sources were used to determine the number of civilian casualties, which explains the disparity in figures – when sources suggest different numbers of fatalities, monitoring organisations record both the minimum and maximum estimates.
The figures include only civilians killed as a direct result of US air strikes, not those killed by other forms of fighting or by air strikes carried out by US allies.
US air strikes were at their heaviest during the invasion of Iraq in 2003, when the military declared 18,695 strike sorties, and in the campaign against the Islamic State (IS) group, which saw more than 9,000 strikes a year from 2015-2017. Before the invasion of Afghanistan, the US air force did not have a single armed drone.
No fewer than 5,529 civilians were killed by alleged US strikes in 2003, making it probably the worst year in terms of fatalities. These strikes were almost all part of the invasion of Iraq.
In 2014, the US began its campaign against IS, leading to the intense bombardment of the Iraqi city of Mosul and the Syrian city of Raqqa in 2016 and 2017. Airwars found that at least 4,931 civilians — and as many as 19,623 — were killed by strikes in 2017.
Neither Centcom, the part of the US military responsible for most of these conflicts, nor the US Department of Defense, have ever published estimates for the number of civilians killed by US military action since 9/11. Centcom told Airwars that data on officially recognised civilian harm was not readily available.
In the campaigns against IS in Iraq and Syria, the US-led coalition has accepted killing 1,417 civilians, which is far lower than Airwars’ own estimate of at least 8,300. In 2016, the US admitted killing between 64 and 116 civilians in Libya, Pakistan, Somalia, and Yemen in counter-terrorism operations between 2009 and 2015.
Assessing the ‘War on Terror’
The new findings come as the world evaluates the impact of the US “war on terror”, launched in the aftermath of the 9/11 attacks, in which 2,977 people were killed by al-Qaeda in New York, Pennsylvania and Virginia. The 20th anniversary of the attacks is this week.
In response to the atrocities of 9/11, US President George W Bush launched a war he said would “not end until every terrorist group of global reach has been found, stopped and defeated”. This campaign has come to be known as the “war on terror”, or America’s “forever wars”. Bush said at the time, “Americans should not expect one battle, but a lengthy campaign unlike any we have ever seen.”
This war has spanned the globe and changed the face of the Middle East. As well as the full-scale invasions of Iraq and Afghanistan, the US has initiated targeted drone and air strike campaigns against militant groups in Somalia, Yemen, Pakistan, and Libya.
Brown University’s Cost of War programme found that over 387,000 civilians have been killed as a result of fighting in post-9/11 wars. The number of war refugees and displaced persons stands at 38 million. The US is conducting counter-terror activities in 85 countries.
Tens of Thousands of Civilians Likely Killed in ‘Forever Wars’
Airwars Tally Offers Assessment of the Direct
Civilian Impact of 20 Years of US Airstrikes
(September 6, 2021) — You often find a similar refrain in US media reporting of the cost of two decades of the so-called ‘War on Terror.’ The trope goes something like this: “more than 7,000 US service people have died in wars since 9/11,” an article or news report will say. In the next line it will usually, though not always, try to reflect the civilian toll — but almost exclusively in generalities. Tens, or even hundreds, of thousands.
Ahead of the 20th anniversary of the 9/11 terrorist atrocities, and the subsequent launch of the War on Terror, Airwars has been seeking the answer to one important question — how many civilians have US strikes likely killed in the ‘Forever Wars’?
We found that the US has declared at least 91,340 strikes across seven major conflict zones.
Our research has concluded that at least 22,679, and potentially as many as 48,308 civilians, have been likely killed by US strikes.
The gap between these two figures reflects the many unknowns when it comes to civilian harm in war. Belligerents rarely track the effects of their own actions — and even then do so poorly. It is left to local communities, civil society and international agencies to count the costs. Multiple sources can however suggest different numbers of fatalities, meaning that monitoring organisations like Airwars will record both minimum and maximum estimates.
This accompanying article explains the conflicts we covered and our key findings in a little more detail, before outlining our methodology and data sources.
What Are the ‘Forever Wars’?
In the days after the terrorist atrocities of September 11, 2001, in which 2,977 people were killed by Al Qaeda in New York, Pennsylvania and Virginia, US President George W. Bush announced the start of a new type of war, one without defined borders, boundaries, or timescales.
“Our war on terror begins with Al Qaeda, but it does not end there,” he told Americans. “It will not end until every terrorist group of global reach has been found, stopped and defeated.”
“Americans should not expect one battle, but a lengthy campaign unlike any other we have ever seen. It may include dramatic strikes visible on TV and covert operations secret even in success.”
“Every nation in every region now has a decision to make: either you are with us or you are with the terrorists,” he concluded.
So it came to pass. The War on Terror has been a near global endeavour. By 2017 for example, the US Department of Defense said it had around 8,000 “special operators” in 80 countries across the globe.
Dubbed the ‘Forever Wars,’ this conflict has not had clear territorial boundaries, though we have included in our dataset the seven most intensive US military campaigns. The types of conflict vary significantly but broadly fall into three categories:
• Full invasions and occupations of countries — Afghanistan 2001-2021, and Iraq 2003-2009.
• Major bombing campaigns against the Islamic State terror group — Iraq 2014-2021, Syria 2014-2021, and Libya 2016.
• More targeted US drone and airstrike campaigns against militant and terror groups — Somalia 2007-2021, Yemen 2002-2021, Pakistan 2004-2018, and Libya 2014-2019.
Based on official US military data, we have concluded that the US has carried out a minimum of 91,340 airstrikes throughout the 20 years of the War on Terror.
Particular peaks were seen during the invasion of Iraq in 2003, when the US declared 18,695 strike sorties. The campaign against the so-called Islamic State also saw a sustained peak, with more than 9,000 strikes a year from 2015-2017.
We then gathered together every reliable estimate of civilian harm as a result of US strikes.
Wherever possible we sought to measure civilian harm just from US airstrikes but in some cases, such as the first years of the Iraq invasion, it was impossible to disaggregate airstrikes from artillery fire and other heavy munitions, which were therefore included.
Likewise in some US-led Coalitions it was impossible to determine whether each individual strike was American, though US airpower has dominated all such campaigns.
Based on our comprehensive review of credible sources, we found at least 22,679 civilians were likely directly killed by US strikes since 9/11, with that number potentially as high as 48,308.
The deadliest year came in 2003, when a minimum of 5,529 civilians were reported to have been killed by US actions according to the monitoring organisation Iraq Body Count, almost all during the invasion of Iraq that year. The next deadliest year was 2017, when at least 4,931 civilians were likely killed, the vast majority in alleged Coalition bombing of Iraq and Syria. However, if we include maximum estimates of civilian harm then 2017 was in fact the worst year for civilian casualties, with up to 19,623 killed.
Almost all of the reported civilian deaths from US wars since 9/11 (97 percent) occurred in the two occupations (Iraq 2003-20119, and Afghanistan 2001-2021); as well as in the campaign against the Islamic State in Iraq and Syria (2014-2021).
In 2011, at the peak of its 20-year occupation, the US had more than 100,000 troops in Afghanistan. That conflict came to an end last month when the final US troops left after a chaotic withdrawal. During the Iraq occupation, troops numbers peaked at 166,000 in 2007, though forces withdrew by 2011.
Just three years later and following the rise of so-called Islamic State, the US and its international partners began an aerial bombing campaign against ISIS in support of allies on the ground. Campaigns to force ISIS from the Iraqi city of Mosul and the Syrian city of Raqqa in 2016-2017 saw some of the most intense urban fighting since the Second World War. In Raqqa alone, Coalition strikes reportedly killed at least 1,600 civilians. While the Islamists lost their last territorial stronghold in April 2019, the war continues at a low intensity.
As part of our research, we also sought official US military estimates for the numbers of civilians killed by its own actions since 9/11. Neither CENTCOM nor the Department of Defense have published such findings.
In the Iraq and Syria campaign against ISIS, the US-led Coalition has accepted killing 1,417 civilians — far lower than Airwars’ own estimate of at least 8,300 civilian deaths for that war.
Additionally, in 2016 the US admitted killing between 64 and 116 civilians in Libya, Pakistan, Somalia and Yemen in counter terrorism operations in the years between 2009 and 2015. But it provided no further details, dates or specifics — making assessment of those claims near impossible.
More publicly, the United States has admitted to killing two civilians in Pakistan; thirteen in Yemen; and five in Somalia in recent years. At least 394 and as many as 570 civilians have in fact been killed by US actions in those countries, according to monitoring organisation New America.
Airwars approached CENTCOM, the part of the US military responsible for most of these conflicts, directly for this project. It said data on officially recognised civilian harm was not readily available. “The information you request is not immediately on hand in our office as it spans between multiple operations/campaigns within a span of between 18 and 20 years,” CENTCOM said in an email, requesting instead that we file a Freedom of Information request. Such requests can take several years to get a response, with no guarantee of the information being released.
It’s important to note that Airwars has examined only direct harm from US strikes since 9/11 — with many of our sources providing conservative casualty estimates. We are therefore looking at a fraction of the overall civilian harm in these countries. More than 300,000 civilians have been killed by all parties to these conflicts since 2001, according to the well respected Brown University Cost of War programme.
Even so, we believe this research represents the most comprehensive public assessment available of minimum civilian harm by direct US strikes and actions in the 20 years of the War on Terror.
Parts or all of the data presented here were peer reviewed by multiple experts in the field, and our full dataset has also been published, to enable scrutiny.
That said, we acknowledge that civilian harm monitoring mechanisms have varied and evolved extensively over the past 20 years, and are rarely consistent across organisations and campaigns.
Airwars itself was formed in 2014, and has collated data on many of the US’s conflicts since then, using our all-source monitoring in local languages to gather allegations of civilian harm. However, for much of the data in the years before 2014 and for the entirety of the Afghanistan campaign — which Airwars does not monitor — we are reliant upon other organisations. This section will explain where the data was gathered from.
In Afghanistan the United Nations Assistance Mission in Afghanistan (UNAMA) has released civilian harm data since 2006. This includes likely civilian harm from airstrikes carried out by foreign powers. While the War on Terror was launched by the US, some allies initially joined — including European nations that sent significant contingents to Afghanistan. It was not possible to definitively conclude if all of these strikes were conducted by the US as opposed to allied nations, although the US provided the overwhelming majority of airpower throughout the war.
In the early years of the conflict, for the period 2001-05 before UNAMA was fully operational, we have relied upon an investigative dataset compiled by The Nation, which though well researched did not claim to be definitive.
The US and UK invaded Iraq in 2003 to overthrow President Saddam Hussein, and then maintained an occupation with the support of other nations until withdrawing all forces in 2011. In the vacuum after Hussein was unseated, multiple militant groups, including Al Qaeda in Iraq, a predecessor of the Islamic State, thrived. Hundreds of thousands of Iraqis were killed in ensuing conflict-related violence.
The NGO Iraq Body Count has been collating tolls of civilian harm since the 2003 invasion. It kindly agreed to provide Airwars with all data related to allegations of civilian harm caused by US actions between 2003 and 2013. According to IBC, in many cases such as the initial invasion, and the assaults on the city of Fallujah in 2004, it was near impossible to disaggregate civilian harm caused by airstrikes with artillery and other munitions.
As such, the data from Iraq Body Count presented here relates to deaths caused by airstrikes and explosive weapons. Incidents where only small arms fire was involved have been excluded. As with Afghanistan, it is impossible to know for certain whether each strike was carried out by the US or partner nations, though the US provided the overwhelming majority of airpower throughout the war.
Iraq and Syria 2014-2021
In the years after the Arab Spring rippled through the Middle East and North Africa in 2011, the Islamic State militant group seized a swathe of territory spanning northern Iraq and Syria which was roughly the size of the United Kingdom. From 2014 onwards, the US led an international coalition in a bombing campaign against the group, eventually forcing it to cede its last area of territorial control along the Iraqi-Syrian border in April 2019.
Airwars has monitored civilian harm related to the ongoing seven-year war against the Islamic State since the beginning of the campaign, using a standardised methodology and approach for all our civilian harm monitoring projects. Our researchers conduct daily monitoring of local Arabic-language media and social media in Iraq and Syria, documenting and archiving all claims of civilian harm including those claims reported by the local communities themselves. Each event has a unique assessment online, where an archived version of all sources used is also available. Events are considered ‘live’ — constantly updated as new information is found.
Al Qaeda had a limited presence in Libya following the defeat of dictator Muammar Gaddafi in 2011, and was the target of a small number of US strikes. Then from 2014, an Islamic State affiliate emerged in the country — seizing control of several cities and towns a year later.
Airwars researchers have actively monitored all civilian harm caused by all parties in Libya for many years. Based on hyperlocal media monitoring, and reflecting the same methodology and approach as our Iraq-Syria assessments, we have aggregated the number of alleged civilian deaths related to US strikes against both Al Qaeda and so-called Islamic State in Libya since 2012.
Pakistan, Somalia, and Yemen
In the years after 9/11 the United States launched an initially secret drone campaign targeting militant organisations in Pakistan, Somalia and Yemen. These campaigns led to often significant allegations of civilian harm.
In Pakistan, the data was originally collected by The Bureau of Investigative Journalism, with those archives transferred to Airwars in 2019. There have been no reported US strikes since July 2018.
In Somalia, Airwars has published a comprehensive review of all civilian harm allegations from both suspected and declared US strikes and actions since the conflict began in 2007.
In Yemen, the data from 2002-2016 was originally collected by The Bureau of Investigative Journalism. Airwars has actively monitored the US counter terrorism campaign in Yemen since 2017, and all associated allegations of civilian harm.
Differing Methodological Approaches
In every conflict, those organisations monitoring civilian harm have applied different methodologies. Airwars, TBIJ and Iraq Body Count are for example remote monitors — meaning that they gather all information publicly available and reflect any uncertainties in their findings — for example by using high and low casualty ranges, rather than definitive figures.
UNAMA employs a different methodology for Afghanistan. Based until recently in Kabul, it deployed field researchers in each province to physically investigate where possible sites of alleged civilian harm, and to interview witnesses. While this approach can lead to more certainty about circumstances and casualty numbers in an individual event, it may also mean that some locally reported cases can be missed. UNAMA also does not provide casualty range estimates — publishing just one number of confirmed civilians killed per year.
More information on conflict casualty standards and methodologies can be found at Every Casualty Counts, which publishes global standards on casualty monitoring, based on the expert work of more than 50 specialist member organisations.
