A spokesperson for the Houthi movement Brigadier General Sharaf Ghaleb Loqman on Friday has threatened to launch missiles targeting the United Arab Emirates (UAE).
The Brigadier General said that Abu Dhabi is no longer safe from now on.
Loqman also warned investors in Dubai and Abu Dhabi to take his remarks seriously.
The statement comes amid reported advances by UAE-backed forces on the crucial port city of Hodeidah in western Yemen.
The Houthi movement would effectively be under a land, sea and air blockade if they lose control of the Hodeidah, the country's third-largest city.
Describing coalition reports of advances on the Houthi stronghold of Saada as false, Loqman said the army and People's Committees recovered all lost ground, and were working to recover the districts of Hayes and al-Khokha.
The fighting in Hodeidah - the main gateway for imports of relief supplies and commercial goods - escalated earlier this year following a flurry of Saudi attacks against Yemen.
The United Nations considers Yemen to be the world's worst humanitarian crisis.
