"Some six suicide bombers have attacked the office of Basir Salangi, the governor of Parwan province, in the provincial capital of Charikar city," Seddiq Seddiqi, the spokesman said.
There were no reports of causalities yet, he said. "But some explosions have been reported."
Provincial hospital director Khalili Farhangi said a fight was ongoing. "We can hear helicopters flying above us. There has been an explosion inside his office as well as in the courtyard," he said.
"We have received reports of an insurgent attack on the governor's office in Parwan," Captain Justin Brockhoff, a spokesman for the coalition forces said.
NATO-led international forces were providing assistance to the Afghan-led response, he said.
