Yemen’s Houthi rebels fired a ballistic missile into a military site in southwestern Saudi Arabia on Tuesday.
The Houthi-run Saba news agency, citing a military source, said the Qaher-M2 missile was fired at a Saudi command center in Jizan region near Yemeni border.
The source said the missile hit its target and caused heavy losses. There was no comment from Saudi authorities on the claim.
The Yemeni rebels had used M2 missile for the first time on March 28 by firing three missiles at King Khaled airbase in Khamis Mushait region.
Like the Qaher-1, the new version is a surface-to-air missile (SAM) from the old S-75 (SA-2 'Guideline') air defence system that has been adapted for the surface-to-surface role.
The rebels said the Qaher-M2 has a range of 400 km with a 350 kg warhead and is capable of landing within 5-10 m of its aim point. When it was unveiled in December 2015, the Qaher-1 was said to have a range of 300 km with a 200 kg warhead, the same weight as the one carried by the SAM.
