Three Israeli civilians have been stabbed to death in a settlement near Ramallah in the occupied West Bank.
Another Israeli was wounded in the attack in Halamish. The Israeli army says the attacker was shot and caught.
The attack came near the end of a day of clashes between Palestinians and Israeli forces over new security measures at a Jerusalem holy site.
Three Palestinians were killed and hundreds were hurt in East Jerusalem and the West Bank.
Palestinian President Mahmoud Abbas has said he is freezing all contacts with Israel after it installed metal detectors at the site, known to Muslims as Haram al-Sharif and to Jews as the Temple Mount.
Israel says the extra security is needed after two Israeli policemen were killed near the site a week ago.
On Friday, four Israeli civilians were stabbed in Halamish (also known as Neve Tsuf) after “an assailant infiltrated a private home”, the Israeli army said.
Israeli media reported the victims were a man in his sixties and his son and daughter, both in their forties. Another woman in her sixties is being treated in hospital for injuries sustained in the incident.
The Israeli army said the attacker was a young Palestinian man called Omar al-Abed, who hours before the attack, posted on Facebook linking his actions to events at Jerusalem’s holy site.
He was shot by a neighbour – who was a soldier with the Israeli Defense Forces – and taken to hospital, but his condition was unclear.
