At least seven people have been killed in a U.S. drone strike in the Pakistani area of North Waziristan. As in previous strikes, Pakistani officials say the victims were militants, but the Obama administration’s policy is to deem all adult-male drone targets as militants unless exculpatory evidence is found after their deaths. The strike comes just as the head of Pakistan’s intelligence service, Lieutenant General Zaheer ul-Islam, is preparing to visit the United States for talks later this week.
