Islamist group Al-Shabaab killed at least eight people in Somalia after a twin bombing in the city of Baidoa.

Two explosives detonated on Sunday near a busy junction and a neighbouring restaurant, police said.

Al-Shabaab, which means "the youth" in English, often carries out suicide attacks in the capital Mogadishu in a bid to topple Western-backed government.

"The restaurant and the junction were very busy and the death toll may rise," Police Major Bilow Nurr said.

Al-Shabaab's military operation spokesman said government officials and forces were the prime target.

The blasts follows a car bomb attack in Mogadishu near a park and hotel on Friday that killed 14 people.
