Six Afghan civilians were killed and another was injured when their vehicle hit a roadside bomb planted by Taliban insurgents in southern Afghanistan's Helmand province Friday, authorities stated.

"Women and children were among the victims," Helmand police spokesman Farid Ahmad Farhang told media outlets, adding that they had been travelling in the Musa Qala district of the restive province.

The latest deaths come two days after a report by the United Nations said 1,145 civilians had been killed and 1,954 wounded in the war in the first six months of this year.

The UN blamed 80 percent of the deaths on insurgents, saying more than half were caused by roadside bombs, ignoring the violence committed by US-led occupation troops.
