Four hostages have been freed in a special operation in the Nuseirat refugee camp in central Gaza, Israel’s military says, as Palestinian officials reported more than 100 people killed in strikes in the same area.

Noa Argamani, Almog Meir Jan, Andrey Kozlov, and Shlomi Ziv, were rescued by the Israeli military, intelligence and special forces from two separate locations in Nuseirat, the Israel Defense Forces (IDF) said Saturday.

All four were kidnapped from the Nova music festival on October 7, according to the IDF.

“They are in good medical condition and have been transferred to the ‘Sheba’ Tel-HaShomer Medical Center for further medical examinations,” the IDF added.

News of the rescue came soon after Israel’s military said it was operating in Nuseirat and other areas of central Gaza, where heavy shelling and artillery fire was reported.

At least 107 people have been killed as a result of the operation in Nusairat, Deir al-Balah and al-Zawaideh on Saturday, according to a spokesperson at the Al-Aqsa Martyrs hospital in Deir al-Balah.
