KABUL, Afghanistan (AP) — A suicide bomber riding a motorcycle on Monday killed two Afghan defense ministry staffers and wounded at least nine others after he rammed into a bus carrying soldiers and civilian employees who were returning home from work.

Gen. Kadam Shah Sheem, Kabul military commander, said the bombing took place in eastern Kabul city and targeted a bus full of officers, soldiers and defense ministry staff that had just left a nearby military base. He said one of the dead was an officer and the other a civilian.
