E1, also named "Mevasseret Adumim" or "Mvasseret Adumim" ("Harbinger of Ma'ale Adumim," similar to Mevasseret Zion just outside Jerusalem), is a mostly empty area of 12 square kilometres (4.6 sq mi) near Ma'ale Adumim, though there are Bedouin inhabitants. There are Israeli plans for construction, frozen since at least 2009 under international pressure. Construction is controversial as it would create a continuous Jewish population between Jerusalem and Ma'ale Adumim.
