A car bomb exploded Friday killing its driver outside the office of Somalia's prime minister in the capital Mogadishu, an AFP reporter said.
According to lawmaker Abdullahi Musa, a fellow MP was killed in the car blast, the latest in a string of attacks in Mogadishu, many of them claimed by Al-Qaeda-linked Shebab insurgents.
It appeared that an explosive device had been attached to the car, which exploded outside the heavily fortified walls of the government offices, one of the most secure areas in Mogadishu.
There was no immediate claim of any responsiblity.
The Shebab have been driven out of fixed positions in Somalia's major towns by a UN-mandated African Union force, but still regularly launch attacks that include bombs and guerrilla-style raids.
On Thursday, at least eight people were killed Thursday when a suicide car bomber rammed a convoy in Somalia's northern port of Bossasso.
