A confrontation erupted Tuesday at a Williamsburg synagogue that has been at the center of a long and bitter feud for control of the Satmar Hasidic community.

At least one person was injured in a faceoff between hundreds of members of two opposing factions at Congregation Yetev Lev D'Satmar. Some Hasids complained that they were roughed up by cops while praying, something police denied.

Police had to separate several hundred members of the factions inside and outside the synagogue at 152 Rodney St.

Police estimated the crowd ranged anywhere from 500 to more than 1,000.

Police eventually restored order, and many of the members of the faction from upstate New York retreated to a nearby tent where they have been praying.
