A suicide attack on a convoy of military vehicles belonging to the NATO-led Resolute Support mission during the morning rush hour in Kabul on Wednesday killed four people and wounded 22, public health officials in the Afghan capital said.
There was no immediate word on whether any foreign troops had been hurt in the attack, which hit a group of armoured personnel carriers designed to withstand large blasts.
