MOGADISHU (AP) ― Four people were killed when a car laden with explosives blew up near the parliamentary building in the Somali capital, Mogadishu, a police official said Saturday.

The Somali terror group al-Shabab claimed responsibility for the bombing. Capt. Mohammed Hussein said the car exploded at a checkpoint where it had been stopped by Somali troops.

The dead were soldiers and refugees from an internal refugee camp near the check point, Hussien said.

He said Somali troops had ordered the driver of the car out the vehicle for a search when he detonated the explosives.

Seven children from the camp were wounded in the attack. Al-Shabab did not say the target of the car bomber but al-Shabab has launched a campaign of attacks against Somali parliamentarians. Somali legislators were holding a meeting at the parliament at the time of the attack.
