For the first hour after the blast, the smoke was so thick it was almost impossible to breathe. But even as volunteer medics struggled to see survivors to rescue, Dr Abdulkadir Abdirahman Adan knew it would be the worst day of his 12 years running ambulances in one of the world's most violent cities.
"I got there in about 15 minutes. The first thing I saw was a truck burning. Cars, trucks, motorcycles - all of them burning," the 44-year-old dentist said. "Wherever you looked, there was a part of a body. I remember someone screaming ... I saw a man in a burning car, and we couldn't do anything for him - there were no fire fighters. We did what we could. We transported almost 250 people."
At least 512 people were killed in the suicide truck bombing that ripped through Mogadishu's busiest street on the afternoon of October 14. The blast was Africa's worst ever terrorist attack, and it dealt a shattering blow to a fragile but tangible sense of optimism that Somalia was leaving nearly three decades of war and insurgency behind it. It also cast a critical light on the international community's claims to have al-Shabaab, the al-Qaeda-aligned group believed to be behind the blast, on the run.
Stretched along a perfect sandy beach and blessed with a historic old town and port, Mogadishu once liked to call itself the Pearl of the Indian Ocean.
But today al-Shabaab remains so deeply embedded that it is impossible to describe it as anything other than a city at war, despite being nominally controlled by an internationally recognised government heavily backed by the UN and African Union troops. Roadside bombs, grenade attacks, and shootings shake the city with monotonous regularity.
