On Friday, the U.S. government announced that it killed between 64 and 116 “non-combatants” in 473 counterterrorism strikes in areas outside of Afghanistan. The civilian killings in Libya, Pakistan, Yemen and Somalia occurred between January 2009 and the end of 2015. 

But many researchers and human rights observers challenge those figures. They say the number of deaths could be up to six times as high.
