Human Rights Watch charged on Monday that new Israeli rules for foreigners entering the West Bank risked turning the occupied territory into "another Gaza," cutting residents off from the outside world.
The regulations, which have faced waves of condemnation from the European Union and United States, have also been clouded by uncertainty.
Israeli said the rules, which came into force in October, are aimed at clarifying the procedures surrounding West Bank entry and are being implemented on a two-year trial basis.
They were also revised last year amid widespread criticism.
Despite those revisions, HRW said the measures "threaten to further isolate Palestinians from loved ones and global civil society."
