A suicide car bomber has killed 12 people in an attack aimed at African Union (AU) troops in Somalia, an official has said.
A car laden with explosives was rammed into an AU convoy travelling south-west of the capital, Mogadishu, said local governor Adukadir Mohamed Sidi.
This is the first attack since militant Islamist group al-Shabab vowed to avenge the killing of its leader Ahmed Abdi Godane last week.
He was killed in a US air strike.
Monday’s attack took place on the road between Mogadishu and Afgoye town, some 30km (19 miles) from the capital.
“The car packed with explosives hit one of the armoured trucks,” Mr Sidi told the Agence France-Presse news agency.
“Twelve civilians in a minibus were killed, and 27 others were wounded,” he said.
The BBC’s Mohamed Moalimu in Mogadishu says the injured include AU soldiers.
Mr Sidi told him the wounded were being rushed to hospital in Mogadishu.
Witnesses reported a huge blast and wave of fire, with civilians on the busy highway between the town and the capital caught up in the explosion, AFP reports .
“I saw two minibuses with pools of blood. Many civilians were killed. The explosion was enormous,” it quoted a witness, Ali Muhidin, as saying.
