Relatives of the hostage Bibas family released a statement Saturday describing how their “world came crashing down” when they discovered that Shiri Silberman Bibas and her two young sons, Kfir and Ariel, were left off the list of captives to be released later in the day.

Hamas had announced that it would release four captive female soldiers — Liri Albag, Naama Levy, Daniella Gilboa and Karina Ariev — in a breach of the Gaza ceasefire and hostage release deal, which requires the terror group to prioritize the release of civilian women and children. Silberman Bibas’s husband Yarden Bibas is slated to be released later in the deal’s first phase. The four soldiers were freed in late morning.

After the release of the four, IDF Spokesman Daniel Hagari said Hamas had violated the deal by not first freeing all female civilians. He said Israel would make sure that civilian hostage Arbel Yehud, who is believed by Israel to be alive, is released soon, along with Shiri Bibas and her two small children, Ariel and baby Kfir.
