The attack on the International Security Assistance Force (ISAF) convoy took place in the Darulaman area in the west of the Kabul, near the national museum.
“I can confirm a suicide attack on Dar-ul-Aman road of Kabul on a convoy of foreign forces,” said a spokesman for Kabul’s police chief, Hashmat Stanikzai, adding that casualties were not yet known.
“Several ISAF members are recorded as casualties and there are also several local Afghan casualties,” a spokesman for the NATO-led force said, without specifying whether the victims had been killed or wounded.
One eyewitness said he saw six dead NATO soldiers inside the bus, while a spokesman for the Afghan Ministry of the Interior, Sadiq Saddiqi, said that the dead included one Afghan policeman and three civilians, believed to be students who had been passing by. Mr. Saddiqi said he could not provide information on the NATO casualties.
