Shelling from the Yemeni side of the border killed a Saudi border guard in the kingdom's Al-Harth region, an official with the Ministry of Interior said, adding that forces retaliated. The news comes after the Saudi-led coalition struck a Houthi military convoy transporting arms in the Hard area in Yemen, near Saudi Arabia's Jizan region, Al Arabiya News Channel reported. The border guard was killed after shelling targeted the checkpoint he was stationed in.
