Another image released by the military was said to show the tunnel in Tel Sultan where Sinwar hid in recent months, along with the tissues the IDF used to identify his DNA.
Rear Adm Hagari said the tunnel where Sinwar stayed was close to the underground passage where six Israeli hostages were held and later murdered in August.
Israel’s army has said it believed the 61-year-old Hamas leader moved between Khan Younis and Rafah in the southern Gaza Strip amid the war.
Sinwar was killed on Wednesday after he and his small security detail apparently had a chance encounter with an Israeli patrol in Rafah.
He was cornered in a blasted house, spotted by a drone and then killed by a tank shell, but it was only when troops found his body that they realised who it was.
The Oct 7 attacks planned by Sinwar resulted in Israel’s deadliest ever day, when marauding Hamas fighters charged out of the strip killing 1,200 and taking 250 hostages.
Israel launched immediate air barrages and ground offensives against Hamas in retaliation, which have destroyed much of the strip and forced huge numbers to leave their homes. The Hamas-run health ministry says 40,000 have been killed.
Sinwar’s death and footage of his final moments have drawn a mixed reaction from Gazans. Many said they had been furious with him for bringing Israeli retaliation against them and then hiding in a tunnel while they suffered.
However the release of footage showing him in the moments before he was killed has also prompted many to praise him for fighting to the end.
