Police say more than 20 people, including government officials, are thought to be trapped inside a hotel in Somalia’s capital where security forces are trying to end a siege by al-Shabab extremists.

The siege follows a car bombing in the same area that has killed at least 13 people and injured dozens.

Captain Mohamed Hussein says two of the five attackers have been killed in a shootout with security forces in the assault on the Nasa-Hablod hotel, which is frequented by politicians and other members of Mogadishu’s elite.

Al-Shabab has claimed responsibility for Saturday’s attack that began with a suicide car bomb exploding outside the hotel gate.

The attackers hurled grenades and cut off the building’s electricity as night fell.

The attack comes just a fortnight after 350 were killed in the same city by a massive car bomb..
