Turki Al-Malki stated that "at 16:24 the Royal Saudi Air Defense detected a ballistic missile launch from Sa’dah governorate aimed at Saudi Arabia".He reported that the ballistic missile was launched deliberately by the Iran-backed Houthi militia to target densely populated civilian areas in Najran, Saudi Arabia, where the missile was intercepted and destroyed by the Royal Saudi Air Defense.He continued: “The interception resulted in projection of fragments throughout some residential areas, where it started a fire in a farm owned by a Saudi national. No casualties were recorded up to the time of this release.”Col. Al-Malki added: “This hostile act carried out by the putschists proves that the Iranian regime is still providing the terrorist Houthi armed militia with qualitative capabilities, in flagrant defiance of UNSCRs 2216 and 2231, with the main objective of threatening the Saudi Arabian, regional and international security.”He concluded: “Launching ballistic missiles at densely populated civilian areas is a direct breach of the principles of the international humanitarian law.”The Royal Saudi Air Defense, as well, detected at 14:28 a ballistic missile aimed at Saudi Arabia, which came down in an empty desert with no casualties recorded.--SPA19:23 LOCAL TIME 16:23 GMT
