The Bab Iskender (Arabic: باب اسكندر Iskander's Strait) is the eastern section 2 miles (3.2 km) wide and 16 fathoms (29 m) of the Bab-el-Mandeb straits, which separates Ras Menheli, Yemen, on the Arabian Peninsula and Ras Siyan, Djibouti, on the Horn of Africa. The Yemeni island of Perim divides the strait into two channels, Bab Iskender and Dact-el-Mayun respectively.
The western section of the straits, Dact-el-Mayun, has a width of about 16 miles (26 km) and a depth of 170 fathoms (310 m).
Near the African coast lies a group of smaller islands known as the Seven Brothers.
The straits are about 20 miles (32 km) wide in total.
