UN Secretary-General Antonio Guterres on Monday strongly condemned missile attacks by Houthi insurgents on Saudi Arabia. Guterres "strongly condemns the launch late yesterday of a series of missiles claimed by the Houthis toward cities in Saudi Arabia, including Riyadh," said a UN statement. On Sunday, the militias fired three missiles at Riyadh and four others at the southern cities of Khamis Mushait, Jizan and Najran. The Saudi-led coalition said the attacks all targeted populated areas. It accused Iran of supplying the missiles to the Houthi militias.
