Yemen's Houthi military spokesman said on Sunday evening that the Iran-allied group would disclose within the next few hours details of a new military operation deep inside the United Arab Emirates.
He made the announcement on Twitter but gave no further details.
The Houthis launched a deadly strike on Abu Dhabi on Jan. 17 and a second foiled missile assault on Monday, after UAE-backed Yemeni militias intervened along frontlines where the Houthis had made inroads last year.
The group, battling a Saudi-led military coalition that includes the UAE, have said they aim to punish the Gulf state for backing militias that are blocking their attempts to capture oil-producing regions in Yemen.
The UAE, on the other hand, said that it intercepted and destroyed a ballistic missile launched by Yemen's Houthi rebels towards the Gulf country with no casualties reported, the third such incident this month.
The defence ministry said in a statement that United Arab Emirates "air defenses intercepted and destroyed a ballistic missile launched by the Huthi terrorist group towards the country".
It added that debris fell in an unpopulated area and there were no casualties.
The Emirates affirms its "full readiness to deal with any threats" and will "take all necessary measures to protect the UAE from any attacks", it added.
It also coincides with the Israeli President Isaac Herzog's first official visit to the UAE after the two countries normalised relations in 2020.
However, a statement from his office on Monday said that he will "continue his visit as planned".
The UAE authorities said that the incident had no impact on air traffic, with flight operations proceeding normally.
The incident on Monday marks the third attack on the Emirates this month, with three foreign workers killed in the first assault on January 17 and the second a week later that was intercepted.
The UAE is part of a Saudi-led military coalition that supports Yemen's government against the Iran-backed Huthis.
In 2019, the UAE withdrew its troops from Yemen but remains an influential player.
"This is not going to be the new normal for the UAE," the official told AFP on condition of anonymity.
"We refuse to acquiesce to the threat of Huthi terror that targets our people and way of life," the official added.
The rebels have warned of further attacks on the UAE, which hosts American troops and is one of the world's biggest arms buyers.
"The UAE has world class defence capabilities and is constantly seeking to update them," said the official, adding that the Huthi rebels "must be" designated as a terrorist organisation.
Yemen's civil war began in 2014 when the Huthis seized the capital Sanaa, prompting Saudi-led forces to intervene to prop up the government the following year.
The conflict has killed hundreds of thousands of people directly or indirectly and left millions on the brink of famine, according to the UN which calls it the world's worst humanitarian catastrophe.
