evidence: In addition, about 1,500 Palestinians with West Bank IDs who live in 18 communities on the East Jerusalem side of the Barrier continue to face impediments in travelling between their homes and service centres; they are forbidden from reaching East Jerusalem and are forced to coordinate their access with Israeli forces to cross checkpoints to access basic health and education services as well as markets on the West Bank side of the Barrier. [...] Under international law, the Israeli authorities have the obligation to facilitate the free movement of Palestinians within the Occupied Palestinian Territory. Exceptions to this obligation are recognized only for imperative reasons of security and only in response to specific security threats. The sections of the Barrier running inside the West Bank, together with the associated gate and permit regime, are unlawful under international law (see the International Court of Justice’s advisory opinion on the Legal Consequences of the Construction of a Wall in the Occupied Palestinian Territory, 9 July 2004).
