Anti-Zionists Ultra Orthodox Jews take part in a demonstration against Israel�s separation barrier in the West Bank village of Nilin on September 17, 2008. Anti-zionist Ultra-Orthodox Jews believe Jews are forbidden to have their own state until the coming of the Messiah. Israel says the 650-km (405-mile) barrier is necessary to protect itself from "terrorist" attacks but the Palestinians call it an "apartheid wall" and complain that large chunks of the West Bank are cut off as a result of it. In 2004, the International Court of Justice issued a non-binding ruling declaring parts of the barrier to be illegal and calling for their removal, something Israel has refused to do.
