RIYADH: Saudi Arabia intercepted a Scud missile fired towards the kingdom by Iran-backed rebels in Yemen, the Riyadh-led coalition fighting the insurgents has said. The official Saudi SPA news agency said the missile was destroyed by the kingdom’s air defenses at around 2145 (1845 GMT) on Saturday, around 100 kilometers from its border with Yemen. The Saturday’s incident is the third time Saudi Arabia says it has shot down a Scud fired from Yemen. On Tuesday, the coalition said that a Saudi Patriot missile had downed a Scud fired from the rebel-held Yemeni capital, Sanaa. Riyadh has deployed Patriots designed to counter tactical ballistic missiles, which have been fired occasionally since March when the coalition began air strikes in support of the Yemeni government after Huthi rebels seized Sanaa and advanced towards second city Aden.
