The United Nations and other aid groups already had pulled their global staff from Hodeidah before the rumoured assault.
Hodeidah, Yemen's biggest port and the only port controlled by the Houthis, serves as the lifeline for the majority of Yemen's population, which lives in Houthi-ruled territory.
A source from the Yemeni National Resistance said that a large number of forces from Brigades AlAmalaqah and the Tihama Resistance Forces, armed with modern weapons and in high morale, have arrived at the outskirts of Al Hodeidah city to continue their build-up in the front lines in preparation for the battle of rolling back the Houthi militias and putting and end to the coup plot in Yemen.

Yemen lies beside the southern mouth of the Red Sea, one of the most important trade routes in the world for oil tankers, which pass near Yemen's shores while heading from the Middle East through the Suez Canal to Europe.
He said the coalition wanted the United Nations to take control of the port but it was prepared to take military action if the Houthis refused to withdraw.
Riyadh says the Houthis use the port to smuggle Iranian-made weapons, including missiles that have been launched at Saudi cities - accusations denied by the group and Tehran.
