The United Nations on Friday suspended all travel into areas held by Yemen’s Houthi rebels after more of their staff were detained by the rebels.

In June, the Houthi's detained 11 employees from Yemen as the rebels kept cracking down on areas under their control.

The United Nations said on Friday that the Houthis who control northern Yemen had detained an unspecified number of U.N. personnel, and it was suspending movement in all Houthi-held areas while seeking the detainees' immediate release.

The United Nations has announced that the Houthis, controlling northern Yemen, have detained several UN personnel. In response, the UN has suspended staff movement in Houthi areas while demanding their release.

The move will authorize harsher penalties on the Iran-backed group, which has attacked Israel and disrupted global shipping trade in the Red Sea for over a year.

President Trump announced on Wednesday that he is once again designating the Houthi rebels in Yemen as a terrorist organization. Why it matters: Trump's decision reverses a decision by then-President Biden in 2021 to remove the terrorist designation from the Houthis.

The United Nations (UN) says it has suspended all movement in Houthi-held areas of Yemen after a number of UN personnel were detained by the armed group in the capital, Sanaa. The UN said that it was actively engaging with senior Houthi officials to try to secure the release of all its detained employees.

Yemen's Huthi rebels have detained another group of UN personnel, a United Nations statement said on Friday, after 13 staff were held last June.

UN says it suspends all movement into territory held by Yemen's Houthi rebels after more staffers detained. I was in the packed hall at Davos to hear Trump speak. The audience went from laughter to silence in seconds.
