At least seven people were killed and ten wounded, including four foreigners, when a suicide bomber in a minivan packed with explosives detonated during Kabul’s morning rush hour yesterday, an interior ministry spokesman said. The spokesman said the bomb -- targeting an SUV belonging to a private Canadian security company, GardaWorld -- had gone off in a neighbourhood which is near the interior ministry and north of Kabul airport. He did not confirm the nationalities of the foreigners injured. Interior Minister Massoud Andarabi said that one of those killed was a 13-year-old child heading to school. There was no immediate claim of responsibility.
