ABUJA — A spate of clashes involving government security forces and insurgent groups in northeast Nigeria has caused mass displacement and threatened humanitarian assistance, as armed groups go “house-to-house” hunting for aid workers, the UN said on Friday. “Up to 65,000 Nigerians are on the move following a series of attacks by armed groups on Damasak town, in northeast Nigeria’s restive Borno State”, UN Refugee Agency (UNHCR) spokesperson Babar Baloch told journalists in Geneva. “Initial reports indicate that eight people were killed, and a dozen injured.” Echoing those concerns, the Office for the Coordination of Humanitarian Affairs (OCHA) reported several incidents in the town since April 11. “Humanitarian assets have been targeted, including the destruction of at least five NGO offices and several NGO vehicles, a mobile storage unit, water tanks, a health outpost and a nutrition stabilization center,” said OCHA spokesperson Jens Laerke. Civilian targets Non-State armed actors were also “conducting house-to-house searches, reportedly looking for civilians identified as aid workers”, he said. This was despite the fact that aid operations and humanitarian facilities were a “lifeline for people in northeast Nigeria who depend on assistance to survive”. According to OCHA, the attacks will affect support to nearly 9,000 internally displaced people and 76,000 people in the host community, who are receiving humanitarian assistance and protection. Repeated attacks In the latest reported attack on Wednesday — the third in seven days — UNHCR’s Baloch explained that “up to 80 percent of the town’s population — which includes the local community and internally displaced people as well — had been forced to flee. Assailants looted and burned down private homes, warehouses of humanitarian agencies, a police station, a clinic and UNHCR facility. Describing the situation as “extremely critical”, OCHA’s Laerke insisted that if the attacks continue, “it will be impossible, maybe for longer periods of time, for us to deliver aid to people who desperately need it” – his comments coming as UNHCR noted that its staff had relocated out of Damasak, temporarily, this week. Civilians fleeing the violence include Nigerians and Niger nationals, Baloch said, explaining they had made for Borno state’s capital city, Maiduguri and Geidam town in neighboring Yobe State. Others crossed into Niger’s Diffa region. Years in the making Years of insecurity and insurgency in Nigeria’s northeast have created a massive humanitarian emergency in the Lake Chad basin. To date, it has uprooted some 3.3 million people. “More than 300,000 are Nigerian refugees, more than 50 percent of them are hosted in Niger and Diffa region - where these refugees, where thousands of refugees, are now arriving from Nigeria, already hosts a quarter (of a) million refugees from Nigeria,” Baloch said. — UN news
