The aim of the coalition attack is to cut off supply lines to the rebel-controlled capital.

"The military operations to liberate the city of Hodeida will not be stopped until we secure the city and its strategic port and that won't last too long", he said.

The army on Saturday claimed it had seized the defunct Hodeida airport, which has been in Huthi hands since 2014. "They are besieged from three sides with the fourth side is the sea", Sabaa News Agency quoted a Yemeni source as saying.

Rebel leader Abdulmalik al-Huthi has urged his forces to put up fierce resistance and turn the region into a "quagmire" for the Saudi-led coalition troops.
The port city on the Red Sea handles more than 70 percent of the country's imports.
"The army is moving in on the Houthi militias at the airport and it nearly has entire control of the surrounding areas", said Saba. The Yemen war has claimed some 10,000 lives since the Saudi-led coalition intervened in 2015. Around two-thirds of the country's population of 27 million relies on aid and 8.4 million are already at risk of starving.
