CAIRO, Sept 17 (Reuters) - The Saudi-led coalition said late on Thursday that it thwarted and destroyed four Houthi explosives-laden drones and a ballistic rocket fired in the direction of the southern Saudi city of Jazan, Saudi state media reported. The Saudi-led military coalition intervened in Yemen in 2015, backing forces of the ousted government of President Hadi and fighting the Iran-aligned Houthi group. There was no immediate claim of responsibility by the Houthis, but the group regularly launches drone and missile attacks targeting the gulf kingdom.
