Fierce fighting has been reported after pro-government forces in Yemen, backed by a Saudi-led coalition, launched an offensive on the rebel-held city of Hudaydah, a key port for aid supplies.
The United Arab Emirates confirmed four of its soldiers had been killed and 22 Houthi rebels reportedly also died.
Fighting raged mainly near the city’s airport and the al-Durayhmi area south of the city, media reports say.
The UN Security Council is to hold urgent talks on Yemen on Thursday.
It is the first time the Saudi-led coalition of mostly Gulf states has tried to capture such a well-defended major city in Yemen.
About eight million people are at risk of starvation in the war-torn country and the coastal city is where most aid arrives for people in rebel-held areas.
The Emirati news agency Wam said attacking forces had managed to “liberate areas… in the surroundings of the airport” and captured or killed “dozens” of Iranian-backed Houthis.
It reported the “martyrdom” of the four Emirati soldiers but did not give further details of the fighting.
Medical sources in the region said 22 Houthi fighters had been killed in coalition strikes.
Coalition sources say 18 air strikes were carried out on Houthi positions on the outskirts of Hudaydah on Wednesday.
