The United Nations said on Tuesday that one of its staff members had died in detention in northern Yemen, where the U.N. has repeatedly called for the Houthi movement to free detained U.N. employees.

The United Nations announced the suspension of its activities in Yemen's Saada region, a Houthi stronghold, after the rebels detained multiple personnel there this year.

The United Nations halted operations in Yemen's Sa'ada region after Houthi authorities detained U.N. staff. The move aims to safeguard personnel while negotiating their release and ensuring safe humanitarian delivery.
