Major General Abdulrahman bin Saad Al Shahrani, commander of Saudi Army's 18th Brigade, had been visiting the troops deployed “on the front lines along the southern region when he had come under enemy fire.

Shahrani had been wounded in the attack and hospitalized, but he had later succumbed to his injuries. He is one of the two highest ranking Saudi officers killed in the war with Yemen.

The attack came in retaliation for the Saudi-led aggression against Yemeni people.

Early reports said tens of Saudi troops were killed in clashes with the tribal forces in Najran province, one of the tribal heads said Saturday.
