Israeli security forces say they have killed three Palestinian militants near Jenin camp in the occupied West Bank.
The Israeli army said the group was preparing an attack and that an automatic rifle was found in their car.
Islamic Jihad claimed one of those killed was a member, and vowed a "strong response from the resistance".
The deaths on Sunday came a day after a Palestinian gunman fatally shot an Israeli security guard in Tel Aviv. Another guard killed the attacker.
He is said to have come from the Jenin area.
On Friday, armed Jewish settlers attacked a Palestinian village where a young Palestinian man was shot dead.
Israeli Prime Minister Benjamin Netanyahu praised the security forces' actions in Jenin, saying: "We will continue to take action - everywhere and at any moment - against those who seek to attack us."
The Jenin camp was the focus of a major Israeli operation last month.
Palestinian Prime Minister Mohammad Shtayyeh said: "These horrific crimes in Jenin would not have taken place had the perpetrators not felt safe from punishment."
Hamas, which controls the Gaza Strip, said those killed had been "assassinated" and that Israel would "not escape paying the price".
