General Mohamed Ahmed Jimale, who was recently named new chief of defence forces, was travelling with senior military officials on Sunday when the bomb exploded near Somalia’s defence ministry compound in the capital, Mogadishu.
The death toll could rise as a minibus carrying passengers was also destroyed in the blast.
“A number of soldiers are among the dead,” he said, adding that Jimale had survived the blast. None of the civilians had survived, Aden said.
Armed group Al-Shabab, which has been carrying out frequent attacks aimed at overthrowing the country’s internationally recognised government, has claimed responsibility for the blast.
A huge cloud of smoke billowed over the scene and heavy gunfire was heard in the area.
The wreckage of the civilian minibus was in the street, with a pool of blood under the vehicle. Burning debris littered the area.

Soldiers opened fire in the air to disperse a crowd standing near a car of an electricity company that was destroyed by the powerful blast.
“There is flesh and blood everywhere,” he said looking at the destruction caused by the blast.
The latest attack comes days after Somalia’s President Mohamed Abdullahi Mohamed declared a new war against al-Shabab amid a worsening security situation as the group steps up deadly bombings in the capital and elsewhere.
The group has denounced Mohamed, who was elected as president in February, as an “apostate” and warned Somalis against supporting him.
Al-Shabab has been pushed out of the capital and other major urban areas in Somalia by national and African Union multinational forces, but it continues to carry out deadly bombings. Targets have included hotels, military checkpoints and the presidential palace.
