NEW YORK CITY: Top UN officials on Wednesday warned the Security Council that there is a risk the fragile situation in Yemen could rapidly deteriorate, as they called for both intensified diplomatic efforts and increased humanitarian funding to stave off further instability and ease human suffering.

With Yemen’s economy in free fall and millions in need, they said time is running out to turn “hope into progress.”

The UN’s special envoy for Yemen, Hans Grundberg, and deputy emergency relief coordinator, Joyce Msuya, also highlighted the ongoing detention of UN workers and employees of nongovernmental organizations by the Houthis, a year after dozens were arbitrarily arrested.

“Their continued imprisonment is shameful,” said Grundberg. “I call again, in the strongest terms, for their immediate and unconditional release.”

Msuya echoed this condemnation, saying: “Twenty-three UN staff remain detained. I join the special envoy and the (UN) secretary-general in calling for their immediate release.”
