Three people have been killed in an apparent assassination attempt on the prime minister in the Somali capital Mogadishu, reports say.
Prime Minister Gedi was on a visit to Mogadishu
Ali Mohamed Gedi was unharmed in the explosion set off near his convoy, witnesses said.
Mr Gedi was visiting from Jowhar, where the transitional government is based.
Somalia has been without a functioning national government for 14 years and a transitional parliament, sworn in last year, has failed to end the anarchy.
'Gunmen and grenades'
Mr Gedi was making his second visit to Mogadishu since his appointment at the helm of the transitional government.
Officials said he was travelling from the airport into the centre of the city when his convoy was attacked by gunmen, who hurled grenades and detonated a landmine.
The blast is reported to have hit one of the vehicles in the convoy, and the prime minister's vehicle was also damaged.
At least one of Mr Gedi's bodyguards was reported to be among the dead.
Somalia has been devastated by civil war and anarchy for 14 years.
In May, at least 14 people were killed in a Mogadishu stadium where Mr Gedi was speaking on his first visit to the capital after his appointment.
Sunday's blast comes a day after Somali pirates attacked a US-owned cruise ship sailing off the east African country.
Crew members on the Seabourn Spirit repelled gunmen in speedboats who opened fire on the vessel, in an incident which terrified passengers.
