The Yemeni rebels say they seized thousands of Saudi troops in a recent cross-border attack.
Houthi rebels in Yemen say they have captured a large number of Saudi troops after a major attack near the border between the two countries.
A Houthi spokesman told the BBC that three Saudi brigades had surrendered near the Saudi town of Najran.
He said thousands of soldiers had been captured and many others killed. Saudi officials have not confirmed the claim.
The operation was the largest of its kind since the conflict began, the spokesman said.
Colonel Yahiya Sarea said 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.
