What is the significance of the Bibas family in the Israel-Hamas conflict?

The Bibas family has become emblematic of the October 7th attack's brutality. Hamas is returning the bodies of Shiri Bibas, her husband Yar Den, and their two young sons, Ariel (4) and Kaffir (9 months), who were among the youngest hostages taken. The two Bibas boys in particular have become iconic symbols throughout Israel, representing the conflict's human toll. This marks the first handover of deceased hostages since the ceasefire was signed, making Thursday a particularly painful moment for Israel as the nation mourns these powerful symbols of suffering.
