Taliban kill 8 in Afghan convoy attack

Taliban militants fired rocket-propelled grenades at a convoy on Afghanistan's main highway, killing six private security guards and two police officers.

The attack happened in Wardak province as equipment was being transported from Ghazni city to Kabul. Taliban militants in vehicles opened fire on the convoy about 30 kilometers southwest of Kabul.

This year has been Afghanistan's most violent since the 2001 US-led invasion drove the Taliban from power.
