How far will Egypt go to help Saudi Arabia secure the Red Sea?

Egyptian President Abdel Fattah el-Sisi met with Saudi Crown Prince Mohammed bin Salman at a critical time, as Iran-aligned Houthi rebels seized control of Yemen's Red Sea coast. This led to a Saudi air campaign and repeated attacks on the kingdom's oil infrastructure. Analysts suggest that Egypt, whose Suez Canal revenues depend on Red Sea navigation, is a key partner for Riyadh in protecting its maritime interests.
