At least nine Afghans have been killed by a roadside bomb in the northern province of Baghlan, officials say. Police said all were wedding guests and their car was destroyed in the blast. Thousands of civilians have been killed in fighting between Taliban and Nato-led forces in recent years. Violence is at levels not seen since the militants were driven from power in 2001. The Taliban and other militants routinely use roadside bombings against Nato and Afghan forces. Civilians are often killed. Police in Baghlan said the wedding guests had been travelling from Pul-e-Khumri, the provincial capital, to a village in the same province when their car hit the bomb. "Nine civilians - six women, a child and two men - have been killed," provincial governor Abdul Majeed said. He said the road was frequently used by foreign forces. Baghlan used to be among a number of relatively peaceful northern provinces which have become steadily more violent in recent months.
