A remote-controlled bomb struck a bus just travelling northwest of the Afghan capital on Tuesday morning, killing at least nine passengers, police said. The militant who set off the device was spotted running away from the scene and was captured by local villagers, according to a report of the Associated Press. The bomb was placed under a bridge and was detonated when the bus drove over the span, said Mohammad Zahir, the director of Crime Department for Kabul police. Broken glass and abandoned shoes of victims littered the road near the bus, which was flipped onto its side at the site of the explosion in Paghman district of Kabul province. At least three other people were wounded in the blast, which went off at around 7 a.m. as Afghans were making their way to work. "The person who pushed the button on the remote-controlled bomb was captured by villagers who saw him running," said Abdul Razaq, an Afghan police official in the Kabul area.
