An unmanned U.S. Predator drone flies over Kandahar Air Field, southern Afghanistan, in 2010. A new report questions the U.S. policy of using armed drones abroad to carry out attacks on suspected terrorists.
An unmanned drone armed with Hellfire missiles is shown over southern Afghanistan. A Hellfire missile fired from a drone was used in 2011 to kill an American in Yemen who the Obama administration says was an al-Qaida leader. Another American died in that attack, and a 16-year-old American was killed in a separate drone strike.

October 2011: Men stand on the rubble of a building destroyed by a U.S. drone strike in southeastern Yemen. Among those killed was U.S. citizen Abdulrahman al-Awlaki, the son of U.S.-born cleric Anwar al-Awlaki — who himself was killed by a drone strike the month before.
