HERAT (Afghanistan) - A SUICIDE car bomber targeted a convoy of foreign troops on Friday in Afghanistan's western Herat province, but it was not immediately clear if there were any casualties, a provincial official said.

Violence has surged this year in Afghanistan, sparking fear the country may slide back into anarchy despite the increasing numbers of foreign troops.

The attack hit the convoy as it was coming out of Herat's airport, said Mr Qadir Agha a security officer. Both Nato and the US-led troops operate in Herat which has faced a number of attacks by resurgent Taleban this year. -- REUTERS
