The Houthis had signaled Friday night they planned a release of prisoners, part of their efforts to ease tensions after the ceasefire in the Israel-Hamas war in the Gaza Strip.

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.

The United Nations said on Friday that Yemen's Houthi rebels have once again detained its personnel in the war-wracked country. They were detained in areas controlled by the Iran-backed militia, the UN Yemen office said.

The United Nations on Friday suspended all travel into areas held by Yemen's Houthi rebels after seven more of their staff were detained by the rebels. The Houthis have already detained U.N. staffers,

All official movement of U.N. staff into or within Houth-held areas had been suspended to protect the safety of staff. The U.N. was actively engaging with senior Houthi representatives to demand the immediate and unconditional release of all its detained personnel and partners.

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.
