The clashes came as Nazareth and cities in the West Bank observed a general strike to mourn the victims of the Gaza conflict between Israel and Hamas -- the bloodiest since 2009 -- that has cost more than 500 Palestinian lives in two weeks.
Police spokeswoman Luba Samri said around 200 Arab Israelis in Nazareth clashed with security forces, who responded with water cannons and stun grenades, arresting 10 people after the 3,000-strong demonstration in Israel's largest Arab city.
The outburst of anger came after the bloodiest day of Israel's two-week Gaza operation, when at least 140 Palestinians and 13 Israeli soldiers were killed yesterday.
Shops were shuttered across the West Bank and in Arab towns in Israel, as unions, nationalist and Islamist groups called for a general strike, a call supported by the Palestine Liberation Organisation.
