UAE-backed separatists pull back after seizing Yemen's Aden

In this Friday Aug. 9, 2019 frame grab from video, Southern Transitional Council separatist fighters line up to storm the presidential palace in the southern port city of Aden, Yemen. The separatists backed by the United Arab Emirates began withdrawing Sunday from positions they seized from the internationally-recognized government in Aden. Both the southern separatists and the government forces are ostensibly allies in the Saudi-led military coalition that’s been battling the Houthi rebels in northern Yemen since 2015, but the four days of fighting in Aden have exposed a major rift in the alliance.
