The Bab-el-Mandeb (variously transliterated Mandab or Mandib, and with article "el-" given also as "al-", with or without connecting dashes) meaning "Gate of Grief" in Arabic (باب المندب), is a strait located between Yemen on the Arabian Peninsula, Djibouti and Eritrea, north of Somalia, in the Horn of Africa, and connecting the Red Sea to the Gulf of Aden. It is sometimes called the Mandab Strait in the English language.
Bab el-Mandab acts as a strategic link between the Indian Ocean and the Mediterranean Sea, via the Red Sea and the Suez Canal. In 2006, an estimated 3.3 million barrels (520,000 m3) of oil passed through the strait per day, out of a world total of about 43 million barrels per day (6,800,000 m3/d) moved by tankers.
The distance across is about 20 miles (30 km) from Ras Menheli in Yemen to Ras Siyyan in Djibouti. The island of Perim divides the strait into two channels, of which the eastern, known as the Bab Iskender (Alexander's Strait), is 2 miles (3 km) wide and 16 fathoms (30 m) deep, while the western, or Dact-el-Mayun, has a width of about 16 miles (25 km) and a depth of 170 fathoms (310 m). Near the coast of Djibouti lies a group of smaller islands known as the "Seven Brothers". There is a surface current inwards in the eastern channel, but a strong undercurrent outwards in the western channel.
According to the recent single origin hypothesis, the straits of Bab-el-Mandeb were probably witness to the earliest migrations of modern humans out of Africa, which occurred roughly 60,000 years ago. At this time, the oceans were much lower and the straits were much shallower or dry, allowing a series of emigrations along the southern coast of Asia.
According to Ethiopian Orthodox Tewahedo Church tradition, the straits of Bab-el-Mendeb were witness to the earliest migrations of Semitic Ge'ez speakers into Africa, occurring roughly around the same time as the Hebrew patriarch Jacob.
Suspension bridge 
Middle East Development LLC has issued a notice to construct a bridge passing across the Red Sea that would be the longest suspended passing in the world.
The Bab-el-Mandab is also a sub-region in the Arab League, which includes Djibouti, Yemen, Somalia and the Comoros Islands.
