KABUL, Afghanistan (AP) – Investigators probing a deadly car bombing in the Afghan capital questioned a man detained at Kabul airport with traces of explosives on his hands, officials said Monday, while U.S. authorities warned all Americans in the capital to be inconspicuous.
Taliban rebels claimed responsibility for Sunday’s blast at a U.S. security firm, but officials said they are not ruling out any suspects, including al-Qaida. Hospital officials said 10 people were killed, including three Americans. The company confirmed that three of its American employees had been killed.
