This is from the daily UN OCHA Report on Gaza.

On the night between 31 October and 1 November, the remains of three bodies were transferred to the Israeli authorities. According to forensic tests, they do not belong to any of the 11 deceased Israeli hostages believed to remain in the Gaza Strip.

Given the difficulties of finding the right 11 corpses amongst the tens of thousands under the rubble, perhaps the Palestinians should just carry on doing this. Send the Israelis three random bodies a day on the assumption that eventually, the right eleven should show up.

Going on the conservative assumption of 60,000 dead, that should all be done and dusted in 54 years and nine months.
