RIYADH:  Saudi Arabias air defense forces successfully intercepted a missile launched towards Jizan region by Yemens armed Houthi militia, state media said on Tuesday. The Houthi-run Al-Masirah channel had earlier announced that a Badr 1 missile had targeted Jizan Economic City, where Saudi Aramco is building a 400,000-barrel-per-day refinery that is expected to become fully operational in 2019. There were no immediate reports of damage or casualties. The Iranian-backed Houthis have fired dozens of missiles into various parts of Saudi Arabia in recent months. Most of the missiles have been intercepted by the Saudi military.
