KABUL, Afghanistan — Militants have fired rockets into a U.S. base in Afghanistan, damaging the plane of the chairman of the U.S. joint chiefs of staff while he was on a visit. The top American military chief was not near the plane at the time of the attack and no one was injured.

NATO spokesman Jamie Graybeal says the attack Monday night at Bagram Air Field outside Kabul did not affect U.S. Army Gen. Martin Dempsey's mission in Afghanistan. He says Dempsey had left by Tuesday morning, though it was unclear if he left on the same plane.

Graybeal was in Afghanistan to discuss the state of the war after a string of insider attacks on U.S. military trainers by their Afghan partners.
