DNA testing had found that remains returned a day earlier purportedly of Ms. Bibas, a dead Israeli hostage, were in fact not hers, stirring outrage in Israel.

The remains of a woman killed while in captivity by Hamas was supposedly handed over to Israel on Friday, a day after her body was supposed to be brought back.

Israel says it has identified two of the dead bodies returned by Hamas on Thursday as Ariel and Kfir Bibas – but tests show another body that was expected to be that of their mother Shiri is not hers – and does not match any other Israeli hostage.
