Which strait separates the Arabian Peninsula from the Horn of Africa?

Bab-el-Mandeb separates the Arabian Peninsula from the Horn of Africa.

The strait connects the Red Sea with the Gulf of Aden and the wider Indian Ocean. Yemen lies on the Arabian side, while Djibouti and Eritrea lie on the African side. Perim, a volcanic island controlled by Yemen, divides the passage into two channels and has long influenced navigation.

The name is Arabic and is commonly translated as “Gate of Tears” or “Gate of Grief.” Bab-el-Mandeb is strategically important because ships travelling between the Suez Canal and the Indian Ocean pass through it. Its importance grew after the Suez Canal opened in 1869, creating a shorter Europe–Asia sea route. It is distinct from the Strait of Tiran, which connects the Red Sea with the Gulf of Aqaba farther north.
