The figures will be disclosed in a review of the US airstrikes worldwide outside of active war zones, Lisa Monaco, President Barack Obama's top homeland security adviser, said Monday.
According to Press TV, the review will include the number of both fighters and civilians who were killed in the air raids.
“In the coming weeks, the administration will publicly release an assessment of combatant and non-combatant casualties resulting from strikes taken outside areas of active hostilities since 2009,” Monaco said during a speech at a Washington think tank.
The report, set to be released following a 2013 promise by Obama to provide more transparency in the assassination drone program, will be published annually, she added.
Jameel Jaffer, a senior official with the American Civil Liberties Union, called the planned report "an important step," but noted it "should be part of a broader reconsideration of the secrecy surrounding the drone campaign."
"The authority to use lethal force should be subject to more stringent oversight by the public, by Congress, and, at least in some contexts, by the courts," Jaffer added.
According to the nonpartisan Stimson Center think tank, the US has drone bases in over a dozen countries, including Afghanistan, Djibouti, Ethiopia, Kuwait, Niger, the Philippines, Qatar, Seychelles, Saudi Arabia, Turkey and the UAE.
