Eleven people have been killed and 16 others injured after a car bomb exploded in a busy market in the Somali capital of Mogadishu on Saturday, local time.
The attack targeted a police station in the Waberi neighbourhood while President Hassan Sheikh Mohamud was visiting a university, said police Captain Mohamed Hussein.
He said the death toll was likely to rise due to the severity of injuries suffered by the victims.
"We have seen children and mothers lying dead," witness Ahmed Ali said. "It's really a very tragic moment for us."
No group has claimed responsibility for the attack, but strong suspicions lie with the al-Qaeda-linked Islamic extremist group al-Shabab, who has waged open war against Somalia's government.
More than 22,000 peacekeepers are deployed in Somalia in the multinational African Union force. Al-Shabab opposes the presence of foreign troops.
