"The mayor and residents of Migdal Haemek share in the heavy grief of the Dahan family, who have recovered the body of their son Shaked, murdered on October 7 while defending the people," the municipality said on its Instagram account.

"His body was recovered in Gaza and returned to his family last night," it said.

The Israeli army said it could not confirm the report.

Hamas's October 7 attack resulted in the deaths of 1,199 people, mostly civilians, according to an AFP tally based on Israeli official figures.

The Palestinian militants also abducted 251 people, 103 of whom are still captive in Gaza including 33 the military says are dead.

Israel's retaliatory military campaign has killed at least 40,534 people in Gaza, according to the territory's health ministry. The UN rights office says most of the dead are women and children.
