Hamas released their bodies last week as part of the Gaza ceasefire deal with Israel, though initially the militant group did not release the correct body for Ms Bibas - causing outrage.
Ms Bibas, 32, was kidnapped with four-year-old Ariel, and nine-month-old Kfir from the Niz Or kibbutz during Hamas's attack on Israel in October 2023.
The four bodies were transferred in black coffins in a carefully orchestrated public display involving dozens of armed Hamas militants - which Israeli Prime Minister Benjamin Netanyahu described as "despicable", and UN human rights chief Volker Turk said was "cruel" and "inhumane".

Thousands of mourners in Israel have gathered on the streets for the funeral procession of Shiri Bibas and her two young sons.
