Jizan, considered the most populous of three Saudi provinces that border Yemen, has witnessed several attacks launched from Houthi militias that killed four Saudi soldiers.

Earlier, the Saudi-led coalition launched Sunday a series of airstrikes on Houthi gatherings in the southwestern city of Taez, according to Al Arabiya News Channel.

The coalition also targeted Houthi-held camps in the Yemeni capital and resumed strikes on Republican Guard bases in the northern province of Saada.

Also on Sunday, the coalition hit a Houthi convoy that was located between Omran province north of Sanaa and Saada.

Meanwhile, violent clashes took place between Houthis and the forces of the Popular Resistance – allied to President Abdrabbu Mansour Hadi – in several cities across Yemen.
