PESHAWAR (AFP) - A roadside bomb blast killed one Shia and wounded six others travelling by mini-bus in an apparent sectarian attack in Kohat on Thursday, police said. Seven people were injured in the bomb blast, local police official Shafiq Khan told AFP. It appears to be a sectarian attack as all the passengers in the van were Shias, he said. The blast was caused by a crude, makeshift device, he said. Another police official, requesting anonymity, said one of the wounded died in hospital and that three of the wounded were in a serious condition.
