Seven children were killed in a U.S.-led coalition air strike targeting suspected insurgents in eastern Afghanistan, a coalition statement said Monday. The strike came hours after the deadliest insurgent attack since the Taliban fell in 2001. Police said Monday they had detained a suspect in connection with the deadly suicide bombing that destroyed a bus full of police instructors at Kabul's busiest transportation hub, killing 35 people and wounding 52, the Associated Press reported. In an operation backed by Afghan troops, jets on Sunday targeted a compound that also contained a mosque and a madrassa, or Islamic school, in the Zarghun Shah district of Paktika province. Early reports indicated seven children at the madrassa and "several militants" were killed, and two militants detained, the statement said.
