Yemen is facing a new political crisis. On Sunday, separatists in southern Yemen declared self-rule in the port city of Aden and nearby provinces. The separatists have the backing of the United Arab Emirates. The Saudi-backed Yemeni government blasted the move, warning of “dangerous and catastrophic consequences.” The two factions had been on the same side in the U.S.-backed war against the Houthi rebels. This comes as the United Nations is attempting to secure a nationwide truce in a bid to contain the coronavirus.
