Burundian refugees who returned from a camp in Tanzania look at the flag of Burundi after arriving by bus at a transit camp in Musenyi, southern Burundi, November 14, 2012. That year, Tanzanian authorities closed down Mtabila camp, which at the time sheltered around 40,000 refugees, and forced many to return to Burundi.
