UN officials are appealing for urgent international aid to Yemen as famine looms and thousands of civilians flee a Houthi offensive on the oil-rich city of Marib.
The Iran-aligned Houthi rebel group, which controls the capital, Sanaa, and much of the war-torn country, is pressing ahead with a renewed offensive on the government-held city of Marib. According to the UN, at least four missiles have landed in the city in the last 10 days, killing at least three civilians.
