A man dressed as Santa Claus has fatally stabbed an Arab Christian man in the back during a procession to mark Orthodox Christmas in the city of Jaffa, Israeli police said.
Gabriel Cadis, the head of Jaffa's Orthodox Church Association, was stabbed on Friday night and died hours later at a hospital.
Police spokesman Micky Rosenfeld said six members of an Arab Christian family were in custody today as police investigate.
Witnesses told police the attacker was wearing a red-and-white Santa suit.
Israeli media reported that Mr Cadis had a long-standing dispute with other Arab Christians in Jaffa.
