Over Easter, Palestinian Christians asked their religious leaders to protest Israel's travel permit system.

During Christmas and Easter, Christians normally can travel back and forth to holy sites and visit family using permits from the Israeli Civil Administration.

But 21 Christian organizations and more than 100 lay leaders signed a document circulating in March, claiming that when Easter coincides with Passover, as in 2010, the permits aren't honored under the pretext of security.

"Religious observance does not need permits and the selective process of permit issuance is categorically unacceptable," the Christians wrote.
