No comment from Saudis but its media reported death of a military official on the battlefield in Yemen.
Yemen’s Houthi fighters have claimed the killing of at least eight Saudi soldiers.
Yahya Saree, a military spokesman for the Iran-aligned group, said late on Sunday that fighters attacked the Tadawin camp in the Marib governorate, where Saudi forces are stationed with a ballistic missile.
Several Saudi soldiers were also wounded, Saree said.
There has been no comment from Saudi Arabia on the attack in Marib but its media reported the death of a lieutenant colonel without specifying the circumstances and location of his death.
Yemen has been beset by violence since 2014, when the Houthis overran much of the country, including the capital Sanaa.
The crisis escalated in 2015 as a Saudi-led military coalition launched a devastating air campaign aimed at rolling back Houthi territorial gains.
Yemen is facing “the world’s worst humanitarian crisis” according to the UN, and many people do not have the essentials they need to survive such as food and water.
The UN children’s agency UNICEF has said that millions of children’s lives are at “high risk” as the country moves closer to famine.
