Hamas says it is investigating possible error over hostage body

JERUSALEM/CAIRO, Feb 21 (Reuters) - Hamas said on Friday it was investigating a possible error in identifying human remains handed to Israel under a ceasefire deal as Prime Minister Benjamin Netanyahu threatened retaliation for failing to release the body of hostage Shiri Bibas.

Hamas was due to hand over the bodies of Shiri Bibas and her two sons Kfir and Ariel on Thursday, along with the remains of a fourth hostage under the ceasefire deal that has halted fighting in Gaza since last month.
