Kabul - Two rocket attacks targeting a US military airbase in Afghanistan on early Tuesday damaged the plane of the top US military officer, leaving two people wounded, an officer confirmed.

"Two rockets struck Bagram Airbase last night after mid-night, causing some damage to an aircraft in the airbase. The aircraft was used by General Martin Dempsey, chairman of the US Joint Chiefs of Staff," An officer of the press department of the airbase, who declined to be identified, told Xinhua, adding that General Dempsey left the base later on Tuesday using another plane.

Two maintenance crew members were wounded in the attack, the officer further said.

General Martin Dempsey pays an unannounced visit to Afghanistan on Monday, only one day after a man wearing an Afghan National Police uniform opened fire against US forces, killing one US soldier with the coalition in southern Kandahar province, the latest in the series of insider attacks when Afghan army, police or gunmen in their uniform turned their weapons against coalition forces.
