Israel on Sunday announced that the remains of three hostages had been handed over from Gaza and would be examined by forensic experts, as a fragile month-old ceasefire held.

Since the ceasefire in Gaza took effect on October 10, Palestinian militants had released the remains of 17 hostages, with 11 remaining in Gaza.

Militants have released one or two bodies every few days. Israel has urged faster progress, and in certain cases it has said the remains are not of any hostage. Hamas has said the work is complicated by widespread devastation.

Israel’s military said official identification of these remains would be provided to families first.

The issue has been just one of the disputes holding up full implementation of the US-brokered ceasefire.
