Palestinians have torched a Jewish holy site in the West Bank city of Nablus, amid soaring tensions with Israel.
Rioters set fire to a tomb revered as that of the biblical figure Joseph. The site, where Jews go to pray, was badly damaged.
It came hours after Israeli PM Benjamin Netanyahu called on the Palestinian leadership to stop a wave of attacks.
Palestinian leader Mahmoud Abbas condemned the arson and said the site would be repaired.
Elsewhere in the occupied West Bank, a Palestinian disguised as a news photographer stabbed and moderately wounded an Israeli soldier, the Israeli military said.
It said the Palestinian attacker was shot dead in the incident in the Jewish settlement of Kiryat Arba, next to Hebron.
Violence between the two sides has spiralled, with near-daily stabbings by Palestinians of Israelis this month.
Seven Israelis have been killed and dozens wounded in the stabbings and some gun attacks. At least 30 Palestinians, including several of the attackers, have been killed in the growing unrest.
The upsurge began last month when tensions at a flashpoint holy site in Jerusalem revered by Jews and Muslims boiled over amid rumours Israel planned to relax long-standing rules to increase Jewish rights at the complex. Israel has repeatedly denied such claims.
