Hundreds of Burundian refugees aboard the &#39;MV Liemba&#39; making the 3-hour journey down Lake Tanganyika to Kigoma, from where they were transferred to Nyaragusu refugee camp. More than 122,000 Burundian refugees have arrived in Tanzania since the beginning of 2015 fleeing political violence in Burundi. Only able to carry 600 people at a time, the 100-year-old ship travelled day and night between Kagunga and Kigoma. Photo: UNHCR
