A road is being built from the established settlement of Eli, near the Palestinian city of Nablus, leading east to the illegal outpost at Hayovel.
Settlement expansion is a major barrier to an Israeli-Palestinian peace deal.

Israel disputes this, but even under Israeli law, those newer, smaller settlements – known as outposts – which have not received authorisation from the government are deemed, by the Israeli government, to be illegal.
