Iran-aligned Houthis attacked a military training camp in the Yemeni city of Marib on Saturday, killing 60 military personnel and wounding dozens others, Saudi state television said on Saturday evening.
Al Ekhbariya television quoted sources as saying the attack was carried out with ballistic missiles and drones.
A proxy war has been playing out in Yemen between Iran and Saudi Arabia.
The Saudi-led coalition intervened in 2015 to restore the government of President Abd-Rabbu Mansour Hadi, which the Houthis ousted from power in the capital Sanaa and is now based in the southern port city of Aden.
The Houthis, who hold Sanaa and most of Yemen’s big urban centres, deny being puppets of Iran and say they are fighting a corrupt system.
Houthis militants did not immediately claim responsibility for Saturday’s attack.
