President Joe Biden plans to announce an end on Thursday to US support for "offensive operations" in Yemen, National Security Advisor Jake Sullivan said. Biden, in a speech at the State Department, also plans to name a special envoy for Yemen, where the United States has backed a Saudi-led offensive against Huthi rebels, Sullivan said. "He's going to announce an end to American support for offensive operations in Yemen," he said. "That's a promise he made in the campaign he will be following through on." sms-cl/ec
