Two car bombs exploded at Somalia's education ministry in the country's capital Mogadishu next to a busy market. President Hassan Sheikh Mohamud said that at least 100 people have been killed and a further 300 injured.
The attack took place on Saturday and is the deadliest since a truck bomb exploded at the same intersection in October 2017, an attack that left more than 500 people dead.
Although no group has yet claimed responsibility for the bombs, President Mohamud blamed Al Shabaab, an Islamist al Qaeda-linked group.
The first bomb detonated at around 2pm, with the second explosion occurring as emergency services arrived and members of the public gathered to help those injured.
President Mohamud added that many of the injured were in a serious condition and that the death toll was likely to rise.
He said: "Our people who were massacred included mothers with their children in their arms, fathers who had medical conditions, students who were sent to study, businessmen who were struggling with the lives of their families."
