A suicide car bomb targeting a foreign military convoy in the Afghan capital Kabul has killed two civilians.
The attack took place outside a defence ministry building close to the British, Canadian and Pakistani embassies.
Officials said the vehicle used in the attack was badly damaged and the bomber was also killed. Several people were also wounded in the blast.
More than 3,000 people have been killed this year as Afghan and foreign forces battle Taleban fighters in Afghanistan.
The bomber damaged three armoured vehicles, but none of the troops was injured, Associated Press quoted coalition spokesman Lt-Col David Johnson as saying.
The attack took place in Wazir Akbar Khan suburb, which is close to the city centre where many diplomatic missions, politicians and several of the international aid agencies operating in Afghanistan are based.
There has been an increase in suicide bomb attacks in Kabul this year.
Two of the worst suicide attacks in the city have targeted army buses - in all, 65 people were killed.
