Police spokeswoman Luba Samri says the groom and three wedding guests were arrested today.
Samri says they are suspected of incitement and unlawful weapon possession.

Some appear to be stabbing photos of Ali Dawabshe, who died when suspected Jewish extremists firebombed his family home in the West Bank in July.
