"The Iranian nation will not hesitate to take any action to deliver its (cargos of) humanitarian assistance to the oppressed people of Yemen," Ali Asghar Ahmadi said.

He also pointed to a cargo ship carrying Iran’s humanitarian assistance to Yemen, saying that the ship’s mission is to deliver the Iranian nation’s humanitarian aid to Yemenis.

The Nejat cargo ship, which belongs to Valfajr Shipping Company, set sail on Monday for the Yemeni port of Hodeida.

On March 26, Saudi Arabia and some of its Arab allies began to launch deadly air strikes against the Houthi Ansarullah movement in an attempt to restore power to the fugitive former President Abd Rabbuh Mansour Hadi, a close ally of Riyadh.

The Saudi-led coalition announced on April 21 that its military operation "Decisive Storm" has ended, but hours later, air strikes and ground fighting resumed.
