A car bomber blew himself up at a checkpoint near Somalia's parliament.

The suicide bomb attack occurred at a checkpoint near Somalia's parliament building, and interior ministry building, in the capital Mogadishu on Sunday.  The city's ambulance service has confirmed that three people have been killed in the attack.

Abdikadir Abdirahman, director of Amin ambulances, the Mogadishu's sole rescue service, said three people had been killed, excluding the bomber, and one person has been injured.

Nur Mohamed, a Mogadishu police officer, told Reuters the bomb had gone off at the heavily guarded Sayidka checkpoint.

The al-Qaeda-linked militant group al-Shabab has claimed responsibility for the car bomb attack.

Al- Shabab frequently carries out bombings and other attacks in Mogadishu in a campaign to topple Somalia's federal government.
