Israel says the remains of three hostages have been handed over from Gaza and will be examined by forensic experts as a month-old ceasefire holds.

Israel announced Sunday that the bodies of three hostages were returned from Gaza and will be examined by forensic experts, as a fragile ceasefire entered its second month.

Israel returned the bodies of 30 Palestinians to health authorities in Gaza on Friday, completing an exchange after militants turned over remains of two hostages, in a sign that the tense Israel-Hamas ceasefire agreement is edging forward.

The Red Cross said it transferred the unidentified remains of three people to Israel late Friday but they were still being examined and may not be those of missing hostages, an Israeli military official said.
