US orders nonemergency government staff to leave South Sudan as tension grows over fighting. An armed group clashed with the country’s army on Tuesday, leading to the arrests of two government ministers and a deputy army chief. The UN Commission on Human Rights in South Sudan on Saturday said that the violence in the north and tension in Juba, the capital, was “threatening to derail” South Sudan’s peace agreement. South Sudan descended into a civil war from 2013 to 2018, during which more than 400,000 people were killed, according to the U.S. State Department. The travel advisory issued on Sunday stated that fighting was ongoing and that “weapons are readily available to the population.” The attack on a U.N helicopter that was on an evacuation mission on Friday was ‘considered a war crime,’ said the UN commission on human rights in South Africa. The president and his rival, Vice President Riek Machar, signed a peace agreement in 2018 that is still in the process of implementation.
