In 2002, religious orders that use a church in Jerusalem got into a fist fight over a chair.

This year, a brawl broke out over an open door.
Ethiopian Orthodox Church
Coptic Church of Egypt
Greek and Russian Orthodox
Franciscans

Okay that’s five of the six groups that fight regularly over the Church of the Holy Sepulchre. There are claims it is on the site of Christ’s crucifixion and resurrection. The rivalry has been going on since the 11th century between these belief groups.
This time six people were injured.
