In June, Somali security officers arrested five AMISOM soldiers from Uganda, which has the largest number of troops in the 22,000-strong mission, and ten civilians for selling military supplies and fuel in the black market in Mogadishu. They were found in a garage in Mogadishu with improvised detonators, fuel, sandbags and empty ammunition boxes.
The police said they caught the men as they were trying to sell the equipment to civilians.
For years, soldiers with AMISOM and the Somali National Army have made extra money by selling military supplies to Mogadishu arms dealers or even their opponents in Islamist militant group al-Shabab.
On Monday, the Somali government pledged to work with the newly-appointed AMISOM force commander, Djiboutian Lieutenant-General Osman Noor Soubagley, to defeat al-Shabab and restore peace to Somalia.
