A police official says that a car bomb close to Somalia's presidential palace detonated while a group of children were walking by, killing five people and wounding seven.

Capt. Mohammed Hussein said most of the dead and wounded were children leaving a video arcade, though he couldn't say precisely how many of the causalities from the Wednesday evening attack were children.

The car bomb attack comes after a bomb blast in Mogadishu on Sunday that killed 15 people.

The Islamic extremist group al-Shabab continues to carry out insurgent-style attacks in the Somali capital as it continues to lose territory to African Union and Somali forces in the countryside.

U.S. forces last month killed the head of al-Shabab in a bombing run but the group quickly named a new leader.
