Saudi Arabia has issued a 24-hour ultimatum to the UAE, demanding the withdrawal of its forces from Yemen. Riyadh cited concerns over alleged UAE support for military escalation near its borders and unspecified weapons shipments. The Saudi Ministry of Foreign Affairs stated that national security is a 'red line' and warned of neutralizing any threats. This warning follows a Saudi-led coalition airstrike on Mukalla, reportedly targeting foreign military support for UAE-backed separatists.
