Which sea separates Saudi Arabia from the African continent?

The Red Sea separates Saudi Arabia from the African continent.

It lies between northeastern Africa and the Arabian Peninsula, with Egypt, Sudan, and Eritrea on its western side and Saudi Arabia and Yemen on its eastern side. The sea connects northward to the Mediterranean through the Suez Canal and southward to the Gulf of Aden through the Bab-el-Mandeb strait.

The Red Sea is a young ocean basin formed as Arabia moved away from Africa. It is known for warm, saline water and extensive coral reefs, especially along its Egyptian and Saudi coasts. The Arabian Sea lies farther southeast, while the Mediterranean lies north of Egypt, so neither separates Arabia from Africa along this route.
