Saudi Arabia bombed Yemen's port city of Mukalla, targeting a weapons shipment it claims originated from the UAE for separatist forces. This action escalated tensions between Saudi Arabia and the UAE, who have backed opposing sides in Yemen. Following the strike and a 24-hour ultimatum from Saudi-backed Yemeni authorities, the UAE announced it is voluntarily withdrawing its remaining forces from Yemen. The UAE denied the shipment contained weapons and stated its presence was for counter-terrorism efforts.
