A Houthi-controlled court in Yemen has sentenced 19 people to death after their conviction for collaborating with the Saudi-led coalition that has been fighting the Iranian-backed rebels for over a decade.

Sunday's verdict, which can be appealed, came a few days after the Houthis and the internationally recognized government in Yemen agreed on the largest prisoner swap in the conflict there, in which 1,600 detainees from both sides will be released.
