Yemen: US urges Houthis to halt advance on Marib
The United States has urged the Houthi rebels in Yemen to halt their advance on the government-held city of Marib, in the north of the country. The US State Department called on the rebels to return to negotiations. The UN says an assault on the city could have unimaginable humanitarian consequences, with hundreds-of-thousands of civilians potentially being forced to flee.
