Unrest in the West Bank has surged alongside the Israel war on the Gaza Strip.

The latest fatality followed an air strike that killed five people on Wednesday in the Tulkarem refugee camp, which Israel's military said targeted "terrorists".

A 27-year-old man was shot dead in Nur Shams refugee camp on the edge of Tulkarem on Thursday, the Palestinian Red Crescent Society and health ministry said.

Rami Elyan, a local official, described the man killed as a civilian not involved in fighting between Israeli forces and Palestinian militants.

The Israeli occupation army said Thursday troops had killed "at least eight terrorists" in Tulkarem in an operation that had already lasted 35 hours.

The occupation army told AFP troops had returned fire and were working to "uncover roads where explosive devices were planted".

A young resident said a bulldozer had been used in Nur Shams and AFP footage showed children playing in the wreckage of a destroyed house, with collapsed walls and debris all around.

"We won't leave the camp. It's our camp," Qais Muhayen al-Shams told AFP, adding the bulldozer had been driven into a house while people were still inside.

Israel has occupied the West Bank since a war with Arab states in 1967, and its troops regularly carry out incursions into Palestinian communities.

West Bank raids have escalated since the Israel war on Gaza began more than three months ago, increasingly lasting days and accompanied by air strikes.

Five Palestinians were also killed Wednesday in an Israeli strike targeting a car in Balata refugee camp near Nablus.

Mourners gathered Thursday for the funeral of one of those killed, whose body was shrouded in a Palestinian flag.

The Red Crescent said its medics treated multiple people wounded in Tulkarem, as well as Ramallah in the central West Bank.

Israeli occupation forces and settlers have killed more than 360 Palestinians in the West Bank since October 7, according to the Palestinian health ministry.

Over the same period, Israeli forces have arrested more than 6,000 Palestinians, according to the Palestinian Prisoners' Club advocacy group.
