Aftermath of the suicide bomber attack
Somalia's state minister for defence has survived an assassination attempt by a suicide bomber in Mogadishu.
Yusuf Mohamed Siyad told the BBC how a car was driven towards his vehicle and explosives on board were detonated, injuring two of his security guards.
Islamist rebel group al-Shabab claimed responsibility for the attack.
The BBC's Mohamed Olad Hassan in Mogadishu says the attack is the latest challenge to a government plan to tackle Islamist insurgents.
Militant groups control much of the south of Somalia and are in constant conflict with the government.
'Committed to kill'
But Mr Siyad said the latest attack would not distract him from his job.
"I used to patrol in the city at midnight and I will keep patrolling until we restore law and order," he said.
"This attack was a message from my enemy that they are committed to kill me and all the other government officials like me but for me it encourages me to be ready."
He told the BBC how after the initial explosion, his vehicle had tried to pick up the two injured guards.
But there were then two more blasts as another vehicle and a wheelbarrow exploded.
Witnesses said at least two bystanders were killed.
In December, an al-Shabab suicide bomber attacked a graduation ceremony for medical students which was attended by senior officials.
Three ministers died at the scene, and another minister died from his injuries last week.
Rumours have been circulating for days that the transitional government is about to launch a major attack on hard-line insurgents.
While hundreds of rebel fighters have poured into the capital in preparation for battle, thousands of civilians have fled the area.
Somalia has been wracked by violence for much of the past 20 years. It has not had a functioning central government since 1991.
