RIYADH: The Organization of Islamic Cooperation has strongly condemned drone attacks on civilians in Saudi Arabia carried out by Houthi militants in Yemen.  The OIC also berated the Iran-backed militia for a ballistic missile attack launched from the Yemeni city of Saada towards the Saudi border city of Najran.  The attack left some civilians injured after fragments of the missile fell on them. The Arab coalition intercepted and destroyed the Houthi missile on Saturday morning. Houthis continue to target civilians and residential areas with ballistic missiles and drones in Saudi Arabia, the OIC said.
