NATO Investigating Airstrike in Afghanistan

It may have hit a handful of campaign workers prepping for the Afghan elections.

An apparent air strike by foreign forces killed six election campaign workers in Afghanistan's north on Thursday, a government spokesman said, and NATO-led forces said they were investigating the incident.

Civilian casualties caused by foreign forces while hunting militants have been a major source of tension between President Hamid Karzai and Western nations. Violence across Afghanistan is at its worst since the Taliban were ousted in late 2001.

Thursday's attack happened in the Rostaq district of Takhar, a relatively peaceful province in the north near Tajikistan, said a spokesman for the provincial governor, unlike areas in the south and east where the resurgent Taliban are mostly active.
