The Red Wave 2 joint drill, which includes naval forces from seven Red Sea countries, started Sunday in Jeddah, according to Saudi Arabia’s official SPA news agency. The participating forces come from Saudi Arabia, Jordan, Egypt, Sudan, Djibouti, Yemen, and Somalia. The exercise “aims to unify and enhance the maritime security of the countries bordering the Red Sea, protect territorial waters and strengthen military cooperation, Commander of the Saudi Western Fleet Vice Admiral Saqr bin Mohammed Al-Harbi said. He added that the drill also aims to enhance cooperation and standardization of military concepts, raise combat readiness and exchange experiences between the participating countries. The exercise comes amid tension in the Gulf after drones hit two oil facilities in the north of Saudi Arabia on Sept. 14. Yemen’s Houthi rebel group initially claimed responsibility for the attack, but Saudi Arabia and the US have blamed Iran for it.
