Independent estimates Taken together, independent estimates from the non-governmental organizations
New America and the
Bureau of Investigative Journalism suggest that civilians made up between 7.27% to 15.47% of deaths in U.S. drone strikes in Pakistan, Yemen, and Somalia from 2009–2016, with a broadly similar rate from 2017–2019. Civilian casualties as a percentage of overall deaths were highest in Yemen and lowest in Somalia. • The first known U.S. drone strike in Yemen was November 3, 2002 (killing al-Qaeda operative
Qaed Salim Sinan al-Harethi), and the most recent U.S. drone strike in Yemen as of the report's publication was May 17, 2020. Over those 18 years, there were 374 reported strikes in Yemen (with the peak being in 2012), which killed a total of between 1,378 and 1,775 people; of the total deaths, between 115 and 149 were civilians. • In Libya, from the end of the
2011 UN-approved military intervention through March 31, 2020, there were 4,500 air, drone, and artillery strikes in Libya, carried out by many
warring Libyan factions and their foreign supporters including the American, Russian, United Arab Emirates, Turkish, and Egyptian governments. The U.S. carried out 550 strikes (from all methods, not just drones), almost all of them in
Operation Odyssey Lightning in 2016. The U.S. strikes killed between 238 and 298 people, of whom between 227 and 277 were combatants, and between 11 and 21 were civilians. • In Somalia, there were a total of 263 U.S. counter-terrorism airstrikes, drone strikes, and ground raids from 2003 to 2021. Of the 263, the majority (202) occurred under the Trump administration. Collectively, between 1,479 and 1,886 people have been killed in the U.S. strikes in Somalia: between 1,389 and 1,696 militants, between 34 and 121 civilians, and between 56 and 69 unknowns. The
Bureau of Investigative Journalism (BIJ) reported the following figures for U.S. strikes from January 2004 through February 2020. For Pakistan, the BIJ figures below cover only U.S. drone strikes; for Yemen, Afghanistan and Somalia, the BIJ figures include both drone strikes and other actions, including airstrikes, missile attacks, and ground operations.
Office of the Director of National Intelligence The
Office of the Director of National Intelligence reported that: • Between January 20, 2009, and December 31, 2015: 473 U.S. strikes "against terrorist targets outside areas of active hostilities" (i.e., outside Afghanistan, Iraq, and Syria) with between 2,372 and 2,581 combatant deaths and between 64 and 116 non-combatant deaths,
i.e., a civilian casualty rate of 2.63–4.30%.
i.e., a civilian casualty rate of 0.2%. Both the 2009-2015 and the 2016 DNI reports state: "Non-combatants are individuals who may not be made the object of attack under applicable international law. The term 'non-combatant' does not include an individual who is part of a belligerent party to an armed conflict, an individual who is taking a direct part in hostilities, or an individual who is targetable in the exercise of U.S. national self-defense. Males of military age may be non-combatants; it is not the case that all military-aged males in the vicinity of a target are deemed to be combatants." As the DNI reports acknowledge, the government's reported numbers of civilian casualties are far lower than estimates from non-governmental organizations. Scholar Nicholas Grossman, who studies drone strikes, wrote that the official figures "systematically underestimated civilian casualties" and notes that independent estimates suggest a substantially higher rate of civilian casualties, which is likely attributable to the government methodology for classifying an individual as a "combatant." DNI explains this discrepancy as the result of three causes: (1) the U.S. government "uses post-strike methodologies that have been refined and honed over the years and that use information that is generally unavailable to non-governmental organizations," such as sensitive intelligence reliably indicating "that certain individuals are combatants" although but are being counted as non-combatants by nongovernmental organizations; (2) that the U.S. government uses "post-strike reviews involve the collection and analysis of multiple sources of intelligence before, during, and after a strike, including video observations, human sources and assets, signals intelligence,
geospatial intelligence, accounts from local officials on the ground, and
open source reporting" and that this often unique set of information "can provide insights that are likely unavailable to non-governmental organizations" and "frequently enables U.S. Government analysts to confirm, among other things, the number of individuals killed as well as their combatant status"; and (3) some terrorist groups and other actors deliberately promote
misinformation "in local media reports on which some non-governmental estimates rely." ==Sources of evidence==
