A Saudi-led military coalition said on Tuesday it had released 200 Houthi prisoners to support peace efforts aimed at ending the nearly five-year war in Yemen. The coalition also said in a statement carried on Saudi state media that it would ease restrictions on Yemeni airspace to allow flights out of the Houthi-held capital, Sanaa, to transport people requiring medical treatment abroad. The Sunni Muslim coalition intervened in Yemen in March 2015 against the Iran-aligned Houthi movement that ousted the internationally recognized government from power in Sanaa.
