Riyadh — The Coalition Command Supporting Legitimacy in Yemen has decided to keep Yemen's main Hodeidah port open for a month, it said on Wednesday, despite a ballistic missile attack by the Iran-aligned Houthis towards the Saudi capital Riyadh.

"Keen to maintain humanitarian aid to the brotherly Yemeni people and as a result of intensified inspection measures, the Coalition Command announces that Hodeidah port will remain open for humanitarian and relief supplies," the Coalition said in a statement carried by Saudi Press Agency.

The Coalition said that ships bringing in fuel and food supplies will also be allowed to enter for another 30 days while proposals made by the United Nations envoy to Yemen are implemented, it added.

The Red Sea port is the country's main entry point for food and humanitarian supplies.

Saudi Arabia shot down a ballistic missile Tuesday over Riyadh fired from Yemen by Iran-backed Houthi rebels.

US ambassador to the UN Nikki Haley described the strike as bearing “all the hallmarks of previous attacks using Iranian-provided weapons” as she announced Washington would be discussing options for Security Council action against Tehran.

The audacious attack follows the downing of another missile last month near Riyadh airport.

“The missile was aimed at populated residential areas in the Riyadh area, and — thank God — was intercepted and destroyed south of Riyadh without any casualties,” a spokesman for the Coalition said.

“The possession of Iranian-manufactured ballistic weapons by terrorist organizations, including the Iran-backed Houthi militia, is a threat to regional and international security,” Turki Al-Maliki added. — Agencies
