KABUL (AFP) - A bomb attack in a crowded market in southern Afghanistan killed 13 people and wounded dozens more on Wednesday in an area at the forefront of the US-led war against the Taliban. Afghan officials said the attack took place in a village near Lashkar Gah, capital of Helmand province, as farmers were receiving seeds being handed out to persuade Afghans to abandon the poppy crops that produce heroin. A NATO official said at least 13 people were killed and dozens more wounded. The bomb was probably a Taliban-style crudely-made improvised explosive device, said the official with NATOs International Security Assistance Force. We dont know the exact cause, but it was likely to be an IED, he told AFP on condition of anonymity. ISAF helicopters evacuated 40 people to nearby hospitals, he said, adding 32 were in serious condition. Afghanistans interior ministry said the bomb was attached to a bicycle and detonated by remote control.
