Five soldiers with the African Union mission in Somalia (Amisom) and 10 Somalis have been arrested for selling military equipment.
The troops were found with unarranged fuel, sandbags, detonators and empty ammunition boxes.
Amisom confirmed the arrests and added that such unprofessional conduct among its personnel is not acceptable.
Authorities identified the five African Union soldiers as Ugandans and belonging to the largest number of troops in the 22,000-strong mission fighting alongside Somali government forces against al-Shabab Islamist militants.
Somalia’s police chief Mohamed Sheikh Hassan Hamud told reporters that the Amisom troops had been under surveillance for a while after allegations that they were involved in illegal trade, BBC reported.
The 15 culprits are expected to appear in court in Mogadishu shortly.
