At least 30 soldiers have been killed and 60 wounded in Houthi strikes on a military base belonging to forces of the Saudi-led coalition in southwest Yemen.
The Houthis carried out several attacks on Sunday using armed drones and ballistic missiles on the al-Anad military base.
Yemeni spokesman Mohamed al-Naqeeb said between 30 to 40 soldiers were killed and at least 60 wounded, adding the death toll may still rise as rescuers were still clearing the scene.
The southern forces are part of the Saudi-led coalition.
Residents said they heard several loud blasts in the al-Anad area, which is about 70 kilometres north of the southern port city of Aden.
Several other residents from the disputed central city of Taiz said they heard ballistic missiles fired from launchers positioned in the Houthi-held eastern suburbs of the city.
The war started in 2014 when the Houthis invaded the capital Sanaa and ousted the government of Abd-Rabbu Mansour Hadi.
A coalition led by Saudi Arabia and the United Arab Emirates intervened in March 2015 to restore Mr Hadi to power but the ensuing conflict, now stalemated, has killed tens of thousands and caused the world's worst humanitarian crisis.
Peace talks between the Saudi-led coalition and the Houthis and backed by the United Nations and the United States, have stalled after both sides failed to reach a compromise deal.
