"The changes grew out of an internal Obama administration debate in the wake of a
March 17 drone attack that the government of Pakistan condemned as a mistake,
saying it killed more than 40 civilians. The U.S. says the attack killed "a
large group of heavily armed men … all of whom acted in a manner consistent with
Al Qaeda-linked militants."..Estimates of noncombatants killed in the strikes vary widely. Long War Journal
counted 14 civilians reported killed in 2010 and 30 in 2011. Some Pakistani and
British activists say the number of civilian deaths is in the hundreds. U.S.
officials, including Democrats
in Congress who oversee the program, insist that the number is far lower. One
U.S. official said there had been "a handful" of civilian deaths in 2011."
