At least one Palestinian has been killed after dozens of Israeli settlers, some wearing masks, attacked a village in the occupied West Bank.
Video on social media showed cars and houses on fire in Jit, near the city of Nablus.
Israel‘s military said petrol bombs and rocks were thrown at buildings and vehicles and that it used “riot dispersal means” to end the violence.
It said one Israeli had been arrested after police and army units intervened in Thursday’s attack.
The Palestinian health ministry reported one person had been killed and another wounded by settlers’ gunfire.
Prime Minister Benjamin Netanyahu and the White House both condemned the attack.
A statement from Mr Netanyahu’s office said he viewed the incident with “utmost severity” and anyone “responsible for any crime will be caught and prosecuted”.
Thursday’s incident is the latest in a series of attacks by settlers – and Palestinians regularly accuse Israeli forces of allowing them to take place.
The US and European countries have consistently urged Israel to do more to stop the attacks.
“Israeli authorities must take measures to protect all communities from harm, this includes intervening to stop such violence, and holding all perpetrators of such violence to account,” said a statement on Thursday from the White House National Security Council.
More than 600 Palestinians have been killed by Israeli fire in the West Bank since the start of the Israel-Hamas war.
These have mostly been during military raids into towns and cities to arrest or kill militants – but civilians are often caught in the crossfire.
Israel accuses Iran of sending money into the West Bank to incite further violence against Israelis.
It also gave approval earlier this year for 3,400 new settlement homes to be built, even though they are illegal under international law.
Israel captured the West Bank, East Jerusalem and the Gaza Strip in the Six-Day War in 1967. All three areas are sought by the Palestinians for an independent state.
Israel, however, considers the West Bank disputed territory and retains control of most of it.

Gaza‘s health ministry said on Thursday that more than 40,000 Palestinians had been killed in the war.
The conflict started after about 1,200 people were killed and many others taken hostage in the Hamas terror attack last October.
Fresh ceasefire talks are currently under way in Doha, with Qatar and Egypt acting on behalf of Hamas.
Previous efforts to end the fighting have failed, apart from a brief pause when some hostages and prisoners were exchanged in November.
