Peace talks being held in Khartoum, Sudan, hit a snag Thursday when a coalition of 14 armed groups suspended their participation, citing the government’s refusal to consider a general amnesty and a unity government. The groups have set a 48-hour deadline for the government to acquiesce to their terms, and have threatened to leave if that doesn’t happen. However, mediators expressed optimism that some kind of deal could be reached. Back on Central African soil, 18 people were killed last Friday when gunmen opened fire at a funeral. In a briefing in late 2017, hournalists wrote about the difficulties U.N. peacekeepers have had in bringing the violence under control.
