The International Court of Justice has ruled that the barrier Israel is building in the West Bank breaches international humanitarian law and cannot be justified by Israel's security concerns.
The ruling, which was carried by 14 to 1 with the only dissenter being an American judge, also found that parts of the barrier should be torn down and that compensation should be paid to those for damages caused in its construction.
Israel has already said it will not accept the ruling, while Palestinians said they would call for UN sanctions against Israel after the ruling.
The ICC's ruling, which is not legally binding, was given at the request of the United Nations General Assembly.
In advance of the ruling, the Israeli government said that the wall has already improved the country's security. However, the Palestinian Authority has described its construction as a land grab.
Israel has already completed 125 miles of fences and walls that are planned to eventually stretch for around 450 miles.
