A suicide car bomb near the entrance of the US embassy in Kabul has killed four people and injured at least 18 others attending a Thanksgiving day event.
The explosion targeted a passing convoy of foreign troops but caught Afghan bystanders as they queued to enter the fortified compound.
The suicide bomber, who was driving a Toyota Corolla, struck at 8.30am, according to Abdullah Fahim, a health ministry spokesman. The blast was about 200 metres from the embassy.
No embassy personnel were killed or injured.
Television pictures showed firefighters extinguishing burning tyres and the smouldering remains of the car.
