Dozens of Arabs have blocked the roads and are throwing rocks and firebombs at the Israel Police and the Border Police on Saturday night, in the Arab neighborhood of Isawiyya in northern Jerusalem.
Most of the crowd has been driven back using riot dispersal measures, police said. There were no casualties reported.
Earlier Saturday night, Palestinian Arabs threw rocks at a bus, breaking the windshield, near the Naomi Shemer exit from the tunnel between Jerusalem and Ma'ale Adumim.
No injuries have been reported; the IDF is scanning the area to find the perpetrators.
Security forces have been prepared on high alert in Jerusalem this weekend, for fear of an attempt by terrorist groups to target Israeli civilians.
