Afghanistan: U.S.-Afghan Tensions Increase as Airstrike Kills More Civilians --- KABUL, Afghanistan — A coalition airstrike in a province north of Kabul killed at least two Afghan villagers Wednesday morning, prompting President Hamid Karzai to order an official inquiry and escalating tensions yet again between the allies over civilian deaths. -- While details of the fighting in the Seya Gerd district of Parwan Province remained sketchy, officials confirmed that a strike had been called in after Afghan and coalition soldiers took heavy fire during a mission to clear the area. The gunfight, which took place in an insurgent stronghold used to carry out attacks on Bagram Air Base, claimed the life of one coalition soldier, at least 10 Taliban fighters and several civilians, though the exact number was not yet clear, coalition and Afghan officials said.
