Ugandan soldiers who were deployed with the African Union in Somalia, have been charged with the killing of a group of civilians at a wedding last month.
Head of the AU troops in Somalia, Maman Sidikou, apologised to the families of the seven wedding guests. The bloc had previously denied the incident took place.
According to Human Rights Watch, the Ugandan soldiers started shooting at men in the wedding after a grenade attack on their convoy.
"We have established that, on that occasion, seven civilians died following an incident involving our troops," Mr Sidikou said in a statement.
"I would like, on behalf of the African Union, to offer my sincere apology for these deaths. We regret these deaths," he added.
