A Somali woman sits on a bed where her son has been admitted to a tented-hospital ward at a free Outpatient's Department (OPD) medical clinic at the headquarters of the Burundi Contingent serving with the African Union Mission in Somalia (AMISOM) at the former National University in the Somali capital Mogadishu, on March 4, 2013. According to the African Union-United Nations Information Support Team (AU-UN IST), since Burundi first deployed it's troops to Somalia in 2007 as part of the AU mission, their free medical facilities have been a lifeline for thousands of civilians that were caught-up and injured during fighting with the Al-Qaeda-affiliated extremist group Al Shabaab in and around Mogadishu, and in 2012 alone, they treated over 50,000 patients at the clinic. The OPD clinic is held twice a week, treating hundreds of civilians and would be more regular but for the limited medical supplies; the Burundians share much of their own resources, as well as distributing those donated by external NGO groups and other organisations.
