The latest death was a 17-year-old boy who the ministry said was shot in the chest by the Israeli army in Jenin.

In addition to 11 killed by Israeli forces, Palestinian health officials said a sick 13-year-old boy also died after Israeli forces prevented him from reaching hospital.

Israeli troops launched their incursion into the northern city of Jenin and its refugee camp early Tuesday and were still present on Thursday afternoon.

The military said Wednesday that Israeli forces had seized dozens of weapons and dismantled multiple bomb-making laboratories.

Four soldiers were wounded in "controlled explosions" or by friendly fire, the army said Wednesday without commenting on the Palestinian casualties.

Speaking Thursday at the site where an Israeli drone strike killed three people, a resident told AFP the trio were unarmed civilians.

At a home damaged during the ongoing raid, a boy said Israeli soldiers stole money, gold and mobile phones.

Jenin refugee camp is home to more than 23,000 people, according to the United Nations.

On Wednesday, Hamas -- which Israel is battling in the Gaza Strip and has a strong presence in Jenin -- called the Jenin raid a "desperate attempt to extinguish the flame of resistance".

More than 280 Palestinians have been killed by Israeli forces or settlers in the West Bank since the Israeli war on Gaza erupted on October 7, health officials say.

Israel has arrested more than 4,000 in raids on various parts of the West Bank since 7 October.
