US Defence Secretary Jim Mattis and Secretary of State Mike Pompeo have both called for a swift cessation of hostilities in Yemen. Mr Mattis said the US wanted to see all sides around the negotiating table and an end to air strikes by the Saudi-led coalition it supports within 30 days.
Separately, Mr Pompeo said UN-led negotiations to help end the three-year war should resume next month. The UN says the conflict has caused the world’s worst humanitarian crisis.
Last week, UN aid chief Mark Lowcock warned that half of the country’s population – about 14 million people – were entirely reliant on external aid for survival and were “pre-famine conditions”.
