Taliban bombers attacked a police convoy of buses outside Kabul, killing more than thirty and wounding fifty. The convoy was carrying graduates from a ceremony on the city's western outskirts. All but two of the dead were police cadets. The cadets were returning to Kabul from a training centre and were about to go on leave. According to the district’s governor, a suicide bomber struck first, followed by a second car bomb explosion detonated between two buses in the convoy. At the time of writing, officials are still trying to confirm the precise number of dead, but witness and sources describe a scene of carnage. In a similar attack last week, fourteen were killed, including some Nepali security guards working for the Canadian embassy.
