Hamas has said it will hand over the bodies of three newly-recovered hostages to Israel on Sunday night.
It comes after Israeli sources said remains of three other people repatriated on Saturday did not match any of the missing hostages.
Sunday’s handover is scheduled to take place at 8pm (6pm UK time).
Israeli Prime Minister Benjamin Netanyahu earlier this week ordered airstrikes on Gaza after it released remains of a hostage who had already been recovered nearly two years ago.
All 20 living hostages were freed under the Gaza ceasefire deal, which began on 10 October.
The remains of 28 dead Israelis were meant to be immediately handed over but Hamas has blamed the ruinous state of Gaza and a lack of equipment for problems locating them all.
Egypt and the Red Cross have been using diggers to help search the rubble.
Israel says latest remains returned from Gaza are not hostages
Israel carries out fresh strike on Gaza and accuses Hamas of preparing ‘imminent terror attack’
Will a night of bombing mean the ceasefire rope finally frays too far?
Seventeen sets of remains have been handed over so far, but the bodies of 11 more hostages are thought to still be in Gaza, including those of two foreign nationals.
Israel has accused Hamas of deliberately stalling.
On Thursday, it said the remains of two hostages returned by Hamas had been confirmed as Sahar Baruch and Amiram Cooper, both taken during the 7 October terror attack.
Israel released nearly 2,000 Palestinian prisoners when the truce began, and has handed over more than 200 bodies, but the violence hasn’t stopped completely.
Gaza health authorities say 236 people have been killed in strikes since the ceasefire began – nearly half are said to have happened in a single day when Israel retaliated for an attack on troops earlier this week.
On Sunday, a Palestinian man was also killed by an airstrike near a vegetable market in Gaza City’s Shejaia suburb on Sunday, according to Gaza’s health ministry and the Al-Ahli Hospital.
Israel said one of its jets had attacked a fighter posing a threat to its force, and that three of its soldiers have been killed during the three-week-old truce.
“There are still Hamas pockets in the areas under our control in Gaza, and we are systematically eliminating them,”
Israeli Prime Minister Benjamin Netanyahu said in a broadcast today.
