Houthi rebels claimed to have captured hundreds of Saudi soldiers in a large-scale offensive in the province of Najran, southwest of the Saudi Arabia, said a Houthi military spokesman, a rebel-affiliated television station Al Masirah reported.
“This is the biggest effort since the beginning of violence against our country”, the spokesman said, without giving further details.
The military alliance led by Saudi Arabia, which is fighting in Yemen against the Houthis fights, did not comment at first.
Since the end of 2014, a war has been raging in Yemen, which, according to UN sources, has plunged the country into the most serious humanitarian crisis worldwide.
Saudi Arabia entered into war with other Arab states in the southern neighboring country in the spring of 2015. The Saudi kingdom wants to push back the influence of its Shiite rival Iran, who supports the Houthi rebels.
The Houthis regularly bombard Saudi Arabia and have also been accused of attacking Saudi oil facilities. They see in it a retaliation for the Saudi bombardments in Yemen.
