At least 40 people have reportedly been killed and dozens wounded in a missile attack and co-ordinated suicide bombings in Yemen.
A health official said the missile targeted a military parade in Aden, the temporary seat of the UN-recognised government, killing several commanders.
Among them, said security sources speaking to Reuters, was Brigadier General Muneer al-Yafee.
He had allegedly just stepped off the stage to greet a guest when the explosion happened.
Soldiers screamed and ran to lift the wounded on to trucks to take to hospital as witnesses described seeing red berets in pools of blood.
Houthi rebel spokesperson Brigadier General Yehia Sarea claimed they had carried out the attack.
He said the soldiers killed were loyal to the UAE, which is a member of the Saudi-led coalition fighting the Iran-backed Houthis since 2015.
Al Masirah TV, the Houthi’s official channel, added the group launched a medium-range ballistic missile and an armed drone.
Earlier in the day, a senior police official said 11 people were killed when a police station was targeted by an explosive-laden bus, car and three motorbikes.
The western-backed Saudi-led coalition intervened in Yemen four years ago to try to restore the internationally recognised government ousted from power by the Houthis the previous year.
Abdu-Rabbu Mansour Hadi’s government controls Aden, a southern port city in Yemen, while the Houthi movement holds most of the biggest urban regions.
Last month the UAE said it was pulling some troops from areas including Aden and another port city Hodeidah, where a UN-brokered ceasefire has been in place since last December.
It is also the main entry point for Yemen’s commercial and aid imports, where scaling back the coalition’s military presence could have paved the way for political talks to end the war.
An Emirati official said the country would not leave a vacuum in Yemen as it had trained 90,000 local forces.
The conflict has so far killed tens of thousands and pushed Yemenis to the brink of famine, and is seen in the region as a proxy war between Saudi Arabi and Iran.
