African Union Transition Mission in Somalia
The African Union Transition Mission in Somalia (ATMIS) is an active African Union transition and drawdown mission from peacekeeping operations in Somalia. Formerly the African Union Mission to Somalia, ATMIS's mandate will end in 2024, with full transition of security operations to the Somali National Armed Forces. ATMIS consists of troops from the East African nations of Burundi, Djibouti, Ethiopia, Kenya, and Uganda. Overview 
The African Union Transition Mission in Somalia was formed on 1 April 2022, following the end of the AMISOM mandate on 31 March. The mission is focused on both military and institutional autonomy of the Somali government as the African Union pulls out. The mission's mandate is set to end on 31 December 2024, when Somali Security Forces are expected to fully take over the security responsibilities of the country, guided by the Somalia Transition Plan. The first reduction of troops to ease into the end of the peacekeeping mission will take place in December 2022. Response from Somalia 
On 6 April 2022, the Prime Minister of Somalia Mohamed Hussein Roble orders African Union Ambassador to Somalia Francisco Madeira persona non grata to leave the country within 48 hours because of "engaging in acts that are incompatible with his status," after audio emerged of him criticizing government officials for not dealing with national security problems. President of Somalia Mohamed Abdullahi Mohamed, a major critic of PM Roble, immediately rejects the expulsion. On 16 April 2022, plans for a new African Union ambassador to come to Somalia to replace Francisco Madeira begin, after the controversy on 6 April that soured relations with the Prime Minister. Major Incidents and Casualties 
 3 May 2022- Al-Shabaab jihadists armed with guns and explosives stormed an ATMIS military camp in El Baraf, Middle Shabelle region, triggering a fierce firefight killing 30 soldiers and wounding another 22 Burundian peacekeepers, according to a high-ranking Burundian military officer. A dozen soldiers were also declared missing. This was the first ever attack on ATMIS since taking over AMISOM on 31 March. 26 May 2023- Heavily armed Al-Shabaab militants stormed an overran an ATMIS military camp in Buulo Mareer, Lower Shabelle region after several car explosions carried out by suicide bombers around the perimeters of the camp. The assault resulted in the deaths of 54 soldiers (per UPDF sources, Al-Shabaab claim 137), and the capture of at least 2 soldiers, along with the militants temporarily seizing control of the town. This attack was the deadliest attack carried out on Ugandan troops since their deployment in Somalia in 2007, and also the deadliest attack on ATMIS troops since their succession of AMISOM on April 2022.
