Houthi rebels in Yemen have claimed they have captured a large number of Saudi troops after a major attack near the border between the two countries.
A Houthi spokesman claimed three Saudi brigades had surrendered near the Saudi town of Najran, reports BBC.
He said thousands of soldiers had been arrested, with many others killed.
Saudi officials have, however, not confirmed the claim.
The spokesman said the operation was the largest of its kind since the conflict began.
Col Yahiya Sarea said the Saudi forces had suffered "huge losses in life and machinery."
All those captured would be paraded on the Houthi-run Al Masirah TV network on Sunday, he added.
Houthis say they launched a drone and missile attack on Saudi oil facilities on 14 September which affected global markets.
Yemen-Saudi conflict
Yemen has been at war since 2015, when Yemeni President Abdrabbuh Mansour Hadi and his cabinet were forced out of Sanaa by the Houthis, who hold much of the northern parts of the country.
Saudi Arabia backs the Yemeni president, and has led a regional coalition against the Irani-aligned rebels.
The civil war has triggered the world's worst humanitarian disaster, with 80% of the population - more than 24 million people - requiring humanitarian assistance or protection, including 10 million who rely on food aid to survive.
More than 70,000 people are believed to have died since 2016 as a result of the conflict, according to UN estimates.
