The Israeli military said on Monday that four more of the Israeli hostages abducted by Hamas on October 7 have died in captivity and that their bodies are being held by the Islamist group.

The military identified the four men as Chaim Peri, Yoram Metzger, Amiram Cooper, and Nadav Popplewell, all of whom were filmed alive in hostage videos posted by Hamas.

Military spokesperson Rear Admiral Daniel Hagari said that new intelligence led to confirmation of their deaths. Hamas had posted a video of Popplewell last month and said that he had died of wounds sustained during an Israeli air strike.

"We estimate the four of them were killed together in the area of (the southern Gaza city) Khan Younis a number of months ago while being held by Hamas terrorists, at the time IDF forces were operating in Khan Younis," Hagari said in remarks that were broadcast.

"We are thoroughly examining the circumstances of their deaths and checking all possibilities. We will present soon the findings, first to their families, and then to the public," he said. "We will present them with transparency, as we have done until now."

Of the more than 250 people abducted on October 7, about 120 remain in Gaza, according to Israeli tallies. Many have been declared dead by Israeli authorities. (Reuters)
