"On May 6, a Central Intelligence Agency drone fired a volley of missiles at a pickup truck carrying nine militants and bomb materials through a desolate stretch of Pakistan near the Afghan border. It killed all the militants — a clean strike with no civilian casualties, extending what is now a yearlong perfect record of avoiding collateral deaths. Or so goes the United States government’s version of the attack, from an American official briefed on the classified C.I.A. program. Here is another version, from a new report compiled by British and Pakistani journalists: The missiles hit a religious school, an adjoining restaurant and a house, killing 18 people — 12 militants, but also 6 civilians, known locally as Samad, Jamshed, Daraz, Iqbal, Noor Nawaz and Yousaf."
