Israel's military says the bodies of two hostages returned by Hamas on Tuesday have been identified as Arie Zalmanowicz and Master Sgt (res) Tamir Adar.

Zalmanowicz , 85, was abducted from his home in Kibbutz Nir Oz during the Hamas-led attack on Israel on 7 October 2023 and killed in captivity on 17 November 2023, the Israel Defense Forces (IDF) said.

Adar, 38, a member of Nir Oz's community security squad, was killed while fighting Hamas gunmen during the 7 October attack. His body was then taken to Gaza.

The return of their remains means that Hamas has transferred 15 out of 28 deceased Israeli hostages under the first phase of a US-brokered ceasefire deal earlier this month.

Their coffins were handed over to troops in the Palestinian territory by the International Committee of the Red Cross, which had earlier received them from Hamas.

The IDF said the coffins - which were escorted by the military - had crossed into Israel and will be taken to be formally identified in Tel Aviv.

Hamas has handed over a Palestinian body in a previous hostage transfers, which it said was accidental due to difficulties locating the bodies.

All 20 living hostages were released shortly after the agreement was reached.

Before the latest remains were identified, the IDF stressed that "Hamas is required to uphold the agreement and take the necessary steps to return all the deceased hostages".

There has been outrage in Israel that Hamas has not yet returned all the deceased hostages.

The Palestinian group says it is trying to do this but that it faces difficulty finding bodies under rubble of buildings bombed out by the IDF in Gaza.

Under the ceasefire and hostage release agreement, Israel has freed 250 Palestinian prisoners and 1,718 detainees from Gaza, and returned 15 bodies of Palestinians for every Israeli hostage's remains.

The first phase of the agreement has also seen an increase of aid into Gaza, a partial withdrawal of Israeli forces, and a halt in fighting - though deadly violence flared up over the weekend as both sides accused one another of breaching the terms of the deal.

The IDF launched a military campaign in Gaza in response to the 7 October 2023 attack, in which Hamas-led gunmen killed about 1,200 people in southern Israel and took 251 others hostage.

More than 68,000 people have been killed by Israeli attacks in Gaza since then, according to the Hamas-run health ministry, whose figures are seen by the UN as reliable. (BBC)
