Saudi forces intercepted seven Yemeni rebel missiles on Sunday, including over the capital Riyadh, in a deadly escalation on the eve of the third anniversary of the Saudi-led coalition’s intervention in Yemen. One Egyptian was killed and two of his countrymen were wounded by falling shrapnel in Riyadh, authorities said, with residents reporting loud explosions and bright flashes in the sky shortly before midnight. The Iran-aligned Huthi rebels fired three missiles at Riyadh and four others at the southern cities of Khamis Mushait, Jizan and Najran, with the coalition saying they all targeted populated areas. This aggressive and hostile action by the Iran-backed Huthi group proves that the Iranian regime continues to support the armed group with military capabilities,coalition spokesman Turki al-Malki said. The firing of multiple ballistic missiles towards cities is a serious development. The Huthi-run Al-Masira television channel claimed the rebels had targeted Riyadh’s King Khalid International Airport as well as other airstrips in the south of the kingdom. The strikes come after the US defence secretary last week urged Saudi Crown Prince Mohammed bin Salman during his visit to Washington to pursue urgent efforts to end Yemen’s wrenching conflict.
