Houthi group said Friday its forces seized 15 Saudi sites in south of Saudi Arabia, a claim denied by the Saudi-led coalition backing legitimacy in Yemen.
During the three last days, Houthi forces took over 15 sites of the Saudi army in Jizan and Najran, Houthi spokesman said.
"All attempts by Saudi army and mercenaries, to retakecontrol over the strategic heights overlooking vast areas, failed," Yahiya Sarie added.
The Saudi "regime has not respected accords on keeping Monabih areas as humanitarian corridors away from any fighting. It has rather pushed its troops to those areas, making locals there confronting the Saudi advance themselves," rebel spokesman said.
An official source at the Arab coalition dismissed the Houthi "allegations on their control over sites in Najran and Jizan."
The Yemeni army, backed by the coalition, has now control of as "deep as 10 kilometers in Sa'ada and Hajja, the spokesman claimed, while Houthis are daily inflicted so pitter losses that they resort to lies."
Houthi claims are "fictional stories to be added to hundreds of Houthi fabrications and fake wins, last of which was an attack on a military site in Dammam," the coalition official added.
Since mid-May, Houthis have intensified firing ballistic missiles and launching drone attacks on Saudi territory "in reply to coalition airstrikes that target Yemeni civilians and infrastructure."
Yemen has been racked by a 4-year bloody conflict between the Yemeni government's forces, backed by a Saudi-led coalition, and the Iranian-backed Houthi rebels who ousted the government in 2014.
The conflict has triggered what the UN calls the world's worst humanitarian crisis, with most of the population in need for a type of humanitarian aid and immediate protection, including 14 million people risking famine and some 1.8 million children suffering malnutrition.
