Saudi soldiers with their weapons stand guard at the Yemen border in Jizan, Saudi Arabia.

A Saudi general has been killed in the south of the country near the border with Yemen, where he had been “defending the country,” the army announced Sunday.

Brigadier General Ibrahim Hamzi, deputy commander of the 8th brigade in Jazan, died from his injuries after being taken to hospital, the Saudi Press Agency reported.

He is the second high-ranking Saudi military official to have been announced killed on the Yemen border this weekend.

A colonel and another border guard were killed late Friday in a gun battle after a landmine blast along the frontier with Yemen, according to the interior ministry.

Several other Saudi soldiers have also been killed since March when the kingdom formed an Arab coalition to fight Houthi militias in Yemen.

In June, a Saudi lieutenant colonel died in a landmine blast in Jazan, while another general was killed in cross-border fire in August.

Riyadh launched air strikes against the Houthis to support the internationally-backed government of Yemeni President Abdrabbu Mansour Hadi, which was losing ground.

The militias have lost territory since late July when the coalition began deploying ground troops in support of local forces.

Around 70 people have been killed in Saudi Arabia from border shelling and skirmishes since the coalition campaign began. Soldiers have accounted for most of the border casualties.

The United Nations says nearly 4,900 people, including a vast number of civilians, have been killed in Yemen since late March.
