From MSNBC.com:

JERUSALEM – Greek and Armenian priests and worshippers scuffled at the Church of the Holy Sepulcher on Palm Sunday, part of a growing rivalry over religious rights at Christianity’s holiest shrine.

In the fight, a Greek priest was pushed to the ground and kicked, according to witnesses from both sides. Two Armenian worshippers were briefly detained by Israeli police. Scores of Armenian supporters staged a protest outside the police station during the questioning of the two, beating drums and chanting.
