Attacks on a key military airbase belonging to the Yemeni government on Sunday have killed at least 30 service members.
A government spokesperson told NHK that Houthi rebels carried out attacks using missiles and armed drones on Al-Anad military base in the country's south.
President Abd-Rabbu Mansour Hadi strongly condemned the attacks, saying the Houthis will pay a heavy price for the crimes they have committed against the people of Yemen.
The Houthis have not issued a statement on the incident.
The Middle Eastern country has been mired in more than six years of civil war between the Saudi-backed government and Iran-supported Houthis.
The administration of US President Joe Biden has been working to help end the war.
Saudi Arabia and Iran reportedly held talks in April this year, but no end is in sight to the fighting in Yemen, which has been fueling what has been called the world's worst humanitarian crisis.
