3 U.S. soldiers among 29 killed KABUL, Afghanistan, June 20 (UPI) -- Two bombings in eastern Afghanistan killed at least 29 people Wednesday, including three U.S. soldiers, officials said. A motorcyclist wearing what may have been an explosives vest hit NATO and Afghan security forces in Khost, killing three members of the NATO-led security force and an Afghan interpreter, the U.S. Embassy in Kabul and President Hamid Karzai's office said, CNN reported. A Western source told CNN the three security force dead were U.S. soldiers. An additional 17 civilians were killed and 32 injured, the report said. Four children and two women were among eight killed in Logar province when a vehicle hit a roadside bomb planted by the Taliban, a Twitter message from the Interior Ministry said, CNN reported. Karzai's office and the embassy issued statements condemning the attack. The embassy called it "cowardly."
