The new remains were reportedly found in Beit Lahiya in northern Gaza by the extremist groups Hamas and Islamic Jihad.
The remains will be autopsied and identified by Israeli authorities.
Currently, the remains of two hostages killed in Hamas' coordinated attack on Israel on October 7, 2023, remain in Gaza, Israeli Ran Gvili and Thai Sudthisak Rinthalak.
Other remains returned to Israel from Gaza on Tuesday do not match any of the remaining hostages, Israel said.
The announcement comes after the remains – according to the Red Cross, "small parts of a body" – were tested at a forensic institute in Tel Aviv, writes The Times of Israel.
