Officials in the Somali capital of Mogadishu say a bomb explosion near the mayor's convoy Sunday has killed two people and wounded several others.

Mogadishu mayor Mohammed Dheere and his convoy escaped unharmed. He says security forces killed the suspected bomber as he tried to flee.

Dheere told reporters his convoy was traveling on a road north of the city when the explosion occurred. It is unclear whether the device was a remote-controlled bomb or a grenade.

The mayor blames remnants of the Islamic courts movement for the attack.

Last Thursday, the convoy of Interim Prime Minister Ali Mohamed Gedi was also attacked while traveling in Mogadishu. No injuries or deaths were reported in that incident.
