Two bomb blasts targeted a group of lawmakers touring a factory north of Kabul on Tuesday, killing at least 64 people, including five parliamentarians, the deadliest attack in Afghanistan since the fall of the Taliban in 2001, officials said. The bombs went off outside a sugar factor in the northern province of Baghlan as the lawmakers were about to go inside. The twin blasts struck school children, Afghan elders and government officials who had gathered to greet the visiting delegation, officials said. At least 64 people were killed, said a government minister who asked not to be identified because he was releasing information not yet made official. Five members of parliament were among those killed, he said.
