Israeli troops have recovered the bodies of three hostages in the Gaza Strip, with the military saying Friday they were killed in the Oct. 7 Hamas attack and their bodies taken into Gaza.

The military did not say where the bodies were found in Gaza. Israeli forces are currently invading the southern Gaza city of Rafah, saying it’s the last stronghold of Hamas and hostages are being held there.

Around 1,200 people died in the Oct. 7 attack on southern Israel, mostly civilians, and about 250 were taken hostage by Hamas. Around half of those hostages were freed during a cease-fire in November. Israel says militants still hold around 100 hostages and the remains of more than 30 others.

For the 2.3 million Palestinians trapped in Gaza, heavy fighting and Israeli restrictions on land border crossings have hindered the entry food and other crucial supplies.
