Christians in the Gaza Strip will not be allowed to visit holy cities such as Bethlehem and Jerusalem to celebrate Christmas this year, Israeli authorities said on Thursday.

Gazan Christians will be granted permits to travel abroad but none will be allowed to go to Israel and the occupied West Bank, home to many sites holy to Christians, a spokeswoman for Israel's military liaison to the Palestinians said.

Israel tightly restricts movements out of the Gaza Strip, territory controlled by Hamas, an Islamist group that it considers a terrorist organization.
