Palestinian health officials say that four Palestinians have been killed and 44 wounded during a raid by Israeli forces in Jenin, in the occupied West Bank.
One of the dead was Abd al-Rahman Hazem, whose brother shot and killed three Israelis in Tel Aviv in April.
Witnesses said there was a blast and heavy gunfire after dozens of Israeli military vehicles entered Jenin.
The Israeli military said its troops surrounded a house intending to arrest two men suspected of recent shootings.
“An explosive device detonated and the suspects opened fire toward the security forces,” it added.
“The security forces fired back according to standard operating procedures, and the two suspects were killed.”
Palestinian media reported that the troops fired an anti-tank missile at the house during the firefight.
The Israeli military and the Palestinian health ministry said that Abd al-Rahman Hazem was one of the two men killed inside the house.
The official Palestinian news agency, Wafa, reported that the house belonged to his father, Fathi. Israeli security forces are also pursuing the latter in connection with the Tel Aviv attack.
According to the health ministry, two other Palestinian men were shot dead in clashes with the Israeli troops that erupted in the camp.
Reuters news agency reported that the militant groups Islamic Jihad and Al-Aqsa Martyrs’ Brigades said four of their gunmen were killed. One of them worked for the Palestinian Authority’s security services.
Many of the wounded were said to be in critical condition in hospital.
A spokesman for Palestinian President Mahmoud Abbas said: “The Israeli occupation still underestimates the lives of our Palestinian people and is tampering with security and stability by continuing its escalation policy.”
Israel’s Prime Minister, Yair Lapid, tweeted that the Israeli troops had acted “with maximal precision” and that his country would “not hesitate or be deterred to act against anybody who tries to hurt Israeli citizens or our security forces”.
Since January, more than 90 Palestinians, including militants and civilians, have been killed in the West Bank, primarily by Israeli security forces.
Their raids intensified after a wave of deadly attacks by Palestinians and Arab Israelis on Israel’s streets, killing 18 people.
