Israeli forces recovered the bodies of six Israeli hostages from the Khan Younis area of southern Gaza in an overnight operation, the Israeli military said on Tuesday, highlighting the plight of the scores of captives remaining in the Palestinian enclave.

The military named the hostages whose bodies were returned to Israel as Yagev Buchshtab, Alexander Dancyg, Avraham Munder, Yoram Metzger, Nadav Popplewell and Haim Perry. All but Mr. Munder were already known to have died in captivity.

They were among about 250 people taken hostage last Oct. 7, when Hamas-led militants crossed into Israel from Gaza and carried out attacks that killed about 1,200 people, according to Israeli authorities.

This is a developing story.
