Clashes erupted in the West Bank overnight following an attack on a mosque, which saw vandals setting fire to a library and spraying hate messages in Hebrew.
The attack has been blamed on hardline Jews angered by plans to curb settlement building.
Local villagers hurled stones at Israeli troops sent to investigate the overnight incident at the mosque in the northern West Bank's Yasuf village.
The security forces responded with tear gas.
One of the slogans sprayed on a wall read: 'Get ready to pay the price.' Another read: 'We will burn you all.'
Village councillors and Palestinian security officials blamed Israelis from a nearby settlement for the attack.
The area is home to some of the most hardline settlers, who advocate a 'price tag' policy under which they target Palestinians in retaliation for any Israeli government measure they see as threatening Jewish settlements.
The Israeli military said 'it appears that the suspects wrote hate-filled messages in Hebrew in addition to burning bookshelves and a carpet.'
It assured the Palestinian Authority that it 'views the incident gravely' and that security forces are working to locate the perpetrators, the statement said.
Last week, a house and three vehicles were set on fire in another village, also near the West Bank city of Nablus.
The owner of the house told police he saw three Jewish settlers start the fires.
Israeli settlers have expressed outrage over the government's decision to impose a 10-month moratorium on new building permits for Israeli homes in the occupied West Bank, outside annexed Arab east Jerusalem.
Settler leader Danny Dayan condemned the attack on the mosque as 'idiotic and outrageous' and harmful to the settlers' cause, according to Israeli public radio.
