Foreign Ministry Spokesman Bahram Qassemi deplored the terrorist attack on Sunday, and extended his condolences to the Somalian people and bereaved families of the victims.
At least 190 people were killed and many others were wounded in what seems to be the largest suicide car bombing ever in the Somali capital Mogadishu.
A suicide bomber exploded a vehicle at a busy intersection despite being fired on by security forces, as reported by government officials, medical sources and witnesses on Saturday afternoon, sending clouds of white smoke spiraling into the sky.
Most of those killed were civilians, police officer Mohamed Dahir said.
Witness Ahmed Hassan described dozens of public buses destroyed as wounded survivors and panicked people sought safety.
"Dead bodies were scattered around the area,” he said. "I have never seen such a terrible attack. It is like an earthquake in terms of the destruction it has caused.”
