Death toll in 'barbaric' bombing in Somalia rises to 300

At least 300 more are injured, authorities said.

Funerals have begun for the killed who have been found. But the death toll from the attacks is expected to rise, as rescue workers continue attempts to pull victims from the rubble.

Hospitals are overextended and struggling to treat victims, many of whom sustained severe burn injuries. Volunteers have been providing first aid and have transferred many wounded to nearby medical points.

Five Red Crescent volunteers were killed in the explosion and several others injured. Among the killed were also 15 primary school children who were on a school bus at the time of the attack, Abdulkadir Adam, the director of an ambulance service, told the Associated Press.

U.N. Secretary General António Guterres said on Sunday that he was “sickened” by the attack, which took place on a crowded street, and sent condolences to the victims.

The Special Representative of the UN Secretary-General for Somalia, Michael Keating, said an “unprecedented” number of civilians had been killed.

“I am shocked and appalled by the number of lives that were lost in the bombings and the scale of destruction they caused,” he said in a statement. “The perpetrators struck a densely populated neighborhood of Mogadishu. They have killed an unprecedented number of civilians. It is a revolting attack both in terms of its intent and impact.”

"Thousands of civilians lose their life in Somalia every year as a direct consequence of the ongoing conflict," said Jordi Raich, ICRC's Head of Delegation, in a statement.
