Israel has received two bodies from Gaza that Hamas says are hostages, the Israeli prime minister's office has said, BBC reported.

The remains, which were transferred via the Red Cross to Israeli forces, were transported to Israel and will be formally identified. Hamas earlier said the bodies had been recovered in the Palestinian territory on Saturday.

Prior to Saturday, the remains of 10 of 28 deceased hostages had been returned to Israel.

The delay has caused outrage in Israel, as the terms of last week's ceasefire deal stipulated the release from Gaza of all hostages, living and dead. Hamas says it has struggled to find the remaining bodies under rubble, according to BBC.
