(BBC) – Some 400,000 children are at risk of starving to death in the Democratic Republic of Congo, the United Nations says. Thousands of families in the Kasai region fled to the bush, where they stayed for months, short of food and water, many have already died. The Kasai region, once one of the most prosperous and peaceful in DR Congo, descended into violence in 2016. Long-simmering resentment exploded into rebellion against the government. In December 2017, the UN declared the crisis in DR Congo as the highest level of emergency – the same as Yemen, Syria and Iraq.
