US warns talks on Yemen truce in 'trouble'

The United States warned Tuesday that talks on Yemen's two-month truce were in "trouble" as it pushed for an extension to help support millions at risk.

Yemen's Saudi-backed government and Iran-aligned Huthi rebels on April 2 entered a UN-brokered truce, the first since the brutal war broke out in 2016, but it expires on Thursday.

Talks to extend the pause in fighting "haven't ended yet but seem to be in a bit of trouble," said Linda Thomas-Greenfield, the US ambassador to the United Nations.

The talks impasse "is troublesome to us," she told reporters.
