Two U.S. soldiers injured by bicycle bomb in eastern Afghanista

BAGRAM, Afghanistan -- A parked bicycle loaded with explosives blew up as a U.S. army patrol passed by in Afghanistan, slightly injuring two U.S. soldiers, a spokesman said Saturday.

The two soldiers, from the 82nd Airborne Division, suffered minor cuts and bruises, said Col. Roger King at the Bagram Air Base.

The bomb exploded Friday afternoon as the patrol's lead vehicle passed near the U.S. base of Salerno, outside the city of Khost.

King called the amount of explosive rigged to the bike a "relatively small amount."

Eastern Afghanistan is one of the most active fronts in the U.S.-led campaign against the remnants of al-Qaida and the Taliban.

and is regarded as one of the least secure parts of the country.
