Dozens of Palestinian youths are clashing with Israeli soldiers in the West Bank city of Hebron, throwing stones and bottles at the troops.
The Israeli forces have responded with tear gas. There are no immediate reports of serious injuries.
Thursday's clashes came a day after a Palestinian teenager was shot dead by Israeli forces in the city, near the Cave of the Patriarchs, a holy site revered by Jews and Muslims.
Tensions have been heightened since Wednesday's shooting. Israel's paramilitary border police force said it shot the 17-year-old after he brandished a gun that later turned out to be fake.
But the Palestinians claimed the youth was unarmed, and had failed to heed orders to halt at a military checkpoint because he was hard of hearing.
