THE death toll from the most powerful bomb blast witnessed in Somalia’s capital rose to 189 with more than 200 injured, making it the deadliest single attack ever in the Horn of Africa nation.

Doctors struggled to assist wounded victims, many burnt beyond recognition. Officials feared the toll would continue to climb from Saturday’s truck bomb that targeted a busy street near key ministries.

Ambulance sirens still echoed across the city as bewildered families looked for missing relatives.

“In our 10 year experience as the first responder in Mogadishu, we haven’t seen anything like this,” the Aamin Ambulance service tweeted.

President Mohamed Abdullahi Mohamed declared three days of mourning and joined thousands of people who responded to a desperate plea by hospitals to donate blood for the wounded victims.

Dr Mohamed Yusuf, the director of Medina hospital, said: “I am appealing all Somali people to come forward and donate,” he said.

“The hospital is overwhelmed by both dead and wounded. We also received people whose limbs were cut away by the bomb. This is really horrendous, unlike any other time in the past.”
