MOGADISHU, Somalia – A Somali police officer says that at least three mortars landed inside Somalia’s heavily fortified presidential palace compound.

Al-Shabab claimed responsibility for the shelling, according the group’s radio station, Andulus. Al-Shabab is an Islamic extremist group in Somalia.

There was no immediate word if Thursday’s attack caused any casualties or damage. The area was sealed off by security forces and journalists could not approach.

Capt. Mohamed Hussein says that two more mortars struck a residential area near the state house which houses the Somali president, prime minister and speaker of the parliament.
