JERUSALEM - Authorities in the northern Israeli city of Acre say Arab and Jewish residents clashed during the Jewish holiday of Yom Kippur.
Police say six Arab rioters were arrested and dozens of cars and shops were damaged.
There were no reports of serious injuries.
The fighting erupted late Wednesday, after the start of Yom Kippur, in a predominantly Jewish neighbourhood of Acre.
Observant Jews fast, pray for forgiveness of their sins and abstain from most activities, including driving, during Yom Kippur, or the Day of Atonement.
Police say an Arab driver entered the neighbourhood and was attacked by Jewish youths who beat him.
Abbas Zakour, an Arab parliament member, said the driver lives in the neighbourhood and was trying to get home.
After the attack on the driver, Arab residents rioted in another area of Acre, damaging cars and shops, police said.
Israel Radio reported that hundreds of car and shop windows were smashed by rocks.
Police dispersed the crowds with tear gas and stun grenades, the report said.
