July 31 (UPI) — Fourteen nations have backed the formation of a Saudi-led coalition to protect shipping routes from Houthi attacks in and around the Red Sea, drawing more countries into the Iran-U.S. war.

The kingdom’s defense ministry announced their support for the multinational defensive maritime alliance Thursday following a meeting in Riyadh attended by the defense ministers and representatives of 43 countries.

According to a statement, the alliance is aimed at “strengthening maritime security, protecting freedom of navigation, securing international trade routes and energy supply routes and safeguarding shared maritime interests in the Bab el-Mandeb Strait, the Red Sea and the Gulf of Aden.”

“The alliance is exclusively defensive in nature and does not target any state, alliance or international organization,” it said.

The statement said participation in the alliance’s activities and operations “will remain a sovereign decision” for each state, meaning any member country can opt out of specific missions.

It also identifies Saudi Arabia its founding state and the alliance’s leader and says thee kingdom will host its permanent headquarters.

A second statement added that other countries that had participated in the meeting “expressed support for the initiative and are in the process of completing the necessary domestic procedures and approvals to join the joint statement.”

The 14 countries are Saudi Arabia, Kuwait, Bahrain, Qatar, Pakistan, Turkey, Egypt, Jordan, Yemen, Bangladesh, Nigeria, Sudan, Djibouti and Somalia, the Saudi Press Agency reported.

The alliance was formed after the Iran-backed, Yemen-based Houthis early last week announced a maritime blockade targeting Saudi vessels traveling through the Red Sea via the Bab el-Mandeb Strait, accusing Riyadh of conducting an “unjust and oppressive siege on our people.”

The blockade threatens energy shipments that exit ports along the western side of the oil-rich nation at a time with Iran is exercising a similar blockade of commercial vessels at the Strait of Hormuz near Saudi Arabia’s eastern side.

The move is expected to further strain energy supplies, potentially causing fuel prices to surge and trigging an international energy crisis. Yemen’s Houthi forces have already claimed to have attacked Saudi oil tankers in the region for allegedly violating its maritime ban.
