Somalia's al-Shabab Islamist group bombed a busy junction and a nearby restaurant on Sunday in the town of Baidoa, killing at least 17 people, a police officer and the group said.

Al-Shabab often carries out such suicide attacks in the capital and elsewhere in its bid to topple Somalia's Western- backed government. The group wants to impose its strict version of Islamic rule in the Horn of Africa nation.

“The restaurant and the junction were very busy and the death toll may rise,” Police Major Bilow Nurr told Reuters from Baidoa, about 150 miles northwest of Mogadishu.

Police Colonel Abdi Osman said the death toll was 17, mostly civilians, with 25 others injured.

A police officer said a suicide car bomb blew up at the junction while a second blast — possibly a bomb that had been planted or a suicide bomber — struck the restaurant.

“We targeted government officials and forces,” al-Shabab's military operation spokesman Sheikh Abdiasis Abu Musab told Reuters, adding there was a police station nearby.

Ismail Olad told Reuters the two locations were full of civilians and security forces. “I heard a huge crash at the busy junction and as I ran, I heard another blast at a restaurant ahead of me. The whole place was covered by smoke,” he said.

The blasts follows a car bomb attack in Mogadishu near a park and hotel on Friday that killed 14 people, police said. He said three militants from the al-Shabab group were also killed.
