African Union soldiers in Somalia have been accused of killing four civilians in the capital, Mogadishu.
Witnesses told the BBC and VoA that the soldiers opened fire on locals when their convoy was hit by a roadside bomb. The victims included the drivers of public transportation vehicles and a dump truck.
The incident happened in the Huriwa district in the north of the city.
A spokesman for the AU Mission in Somalia (AMISOM) said the mission was trying to verify the information, adding that he did not believe any civilians were deliberately killed.
On its Twitter account, the African Union mission said its convoy had come across explosions but made no mention of the shooting, alleged to have involved Burundian troops.
Relatives of the victims have called on the Somali government for justice, while dozens of angry demonstrators took to the streets of Huriwa.
AMISOM has more than 22,000 soldiers and police, from six African countries, deployed in Somalia to protect the government there and fight the militants.
