Members of rival Christian orders have traded blows at the Church of the Nativity in Bethlehem, with four people reported wounded in the fray.

Greek Orthodox and Armenian Apostolic priests were sweeping up at the church following the Christmas rites of the Western churches earlier in the week.

Reports say some Orthodox faithful encroached on the Armenian section, prompting pitched battles with brooms.

Intense rivalries at the jointly-run church can set off vicious feuds.

The basilica, built over the grotto in the West Bank town that is the reputed birthplace of Jesus Christ is shared by Roman Catholic, Greek Orthodox and Armenian religious authorities.
