On October 6, 2013, representatives of the UN Security Council made a field trip to Goma, DRC, site of the biggest, most expensive UN peacekeeping mission in the world and the center of one of the world's most protracted conflicts. The Security Council representatives, among them U.S. Ambassador Samantha Power, met with residents at the Mugunga camp for displaced persons. They also toured the front lines of Congo's battle against the M23, a militia group that according to the UN and U.S. is backed by the government of neighboring Rwanda. They were briefed there by the officers leading the UN and Congolese forces. Portraits from the day, and also from a UN forward operating base at Masisi.
