The U.N. says Houthi rebels in Yemen have removed U.N. equipment and assets from unstaffed offices in Sanaa. The removal, which happened Thursday, included telecommunications equipment and vehicles. This move is expected to hinder humanitarian assistance in Houthi-controlled areas. The U.N. also noted that the Houthis have blocked humanitarian flights to Sanaa and Mareb province for months. These actions come amid ongoing civil war in Yemen, with the Houthis controlling much of the north. The U.N. warns that these restrictions will worsen the humanitarian situation in areas under Houthi control.
