"It has been almost 16 years since a missile fired from a drone struck a Toyota Land Cruiser in northwest Yemen, killing all six of its passengers and inaugurating a new era in American warfare. Today, targeted killings by drones have become the centerpiece of U.S. counterterrorism policy. Although the drone program is swathed in secrecy — the C.I.A. and the military share responsibility for it — American drones have been used to carry out airstrikes in at least eight different countries, analysts believe. Over the past decade, they have also provided reconnaissance for foreign military forces in half a dozen other countries. According to the Bureau of Investigative Journalism, a London-based organization that has been tracking drone killings since 2010, U.S. drone strikes have killed between 7,584 and 10,918 people, including 751 to 1,555 civilians, in Pakistan, Afghanistan, Yemen and Somalia."
