A projectile fired by Yemen's Iran-backed Houthi armed group struck the southern Saudi region of Jazan, injuring at least two people and damaging a mosque, several buildings, and vehicles, according to the Saudi Civil Defence authority.

Citing a report by the Qatar-based media outlet Al Jazeera, the strike hit the Al-Twal governorate in Jazan on Saturday (September 12).

A spokesperson for the Saudi Civil Defence force condemned the incident as a clear violation of international humanitarian law.

Meanwhile, Houthi forces claimed their primary target was a Saudi military base located in Sharurah, Najran province.

With the recent intensification of the Yemeni civil war, the Houthis have increased missile and drone attacks targeting southern Saudi Arabia.

On Tuesday (September 8), Houthi strikes on civilian installations in Abha, Khamis Mushait, Jazan, and Najran injured at least 73 people, including women and children.

Following roughly four years of relative calm mediated by the United Nations, major conflict resumed in Yemen last July.

Houthi fighters have since taken control of Yemen's entire Red Sea coastline as well as the strategic port city of Mocha, while intensifying clashes with government forces in other parts of the country.

According to international organizations, the renewed conflict has already left over 500 people dead and displaced thousands.
