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 was wounded by settlers’ gunfire.
Ibrahim Sadah, a resident of Jit, said there were around 100 settlers who were armed and shooting.
“They [the settlers] were firing, they were firing live bullets,” he said, claiming that the person who was killed was a member of his family: “May he rest in peace, he came to help us like the rest of the youth.”
Another resident, Rabah Sbu Hasan, added: “We were in our houses, and we were surprised by more than 90 people, my children and I were here next to the car… I saw them burning the car, they then set two other cars alight, but my son came to the rescue and had a fight with them and pushed them back.”
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.
Speaking in Israel, Foreign Secretary David Lammy said: “The scenes overnight of the burning and the torching of buildings, of the Molotov cocktails thrown at cars, of the widespread rampage and chasing of people from their homes [are] abhorrent.
“And I condemn it in the strongest of terms.”
He added that he hoped those who engaged in violence are “brought to justice”.
“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 approved 3,400 new settlement homes to be built earlier this year, 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.
