HERAT (AFP) - Five civilians were killed and six wounded when their pick-up truck detonated an improvised explosive device in southwestern Afghanistan, the Governor of Nimroz province told AFP Saturday. The attack was carried out by the Taliban in the district of Bakwan, Farah province, said Governor Ghulan Dastagir Azad, whose province borders Farah. The area where the attack took place is on the border between Farah and Nimroz, he said, adding that the blast occurred as the victims tried to travel to a market regularly targeted by Taliban racketeering. Civilians have become the main victims of the Afghan war. In the first 10 months of 2009, 2,038 civilians were killed in the conflict, 10 per cent more than over the same period in the previous year, according to the UN mission in Afghanistan.
