At least 10,000 people have been Killed in the war in Yemen between Houthi rebels and the Saudi-led coalition supporting the government, the UN says.
The news came as a UN envoy met President Abdrabbuh Mansour Hadi on Monday in the southern city of Aden.
The conflict between the Houthis and the government escalated in March 2015.
The coalition intervened militarily in an attempt to restore the internationally-recognised administration after Mr Hadi was forced to flee the country.
