UN aid chief Mark Lowcock will travel to Yemen this week amid intense diplomacy to end a war that has pushed millions to the brink of famine.
The three-day visit beginning Thursday will allow the UN under-secretary-general for humanitarian affairs to see first-hand the world's worst humanitarian crisis, a UN statement said Wednesday.
UN peace envoy Martin Griffiths is hoping to bring the Saudi-backed Yemeni government and the Huthi rebels to Sweden in the coming days for negotiations on ending the three-year conflict.
At least 8 million people are at risk of starvation in Yemen, but UN aid officials fear four million more will face mass hunger if the fighting continues.
Lowcock, who last visited Yemen in October 2017, will hold talks with officials in the rebel-held capital of Sanaa and in government-controlled Aden.
