On 7 October 2023, as part of the 2023 Hamas-led attack on Israel and the Nir Oz massacre, the Palestinian Islamist militant organization Hamas abducted the Israeli-Argentinian/Peruvian[2][3][4]Bibas (Hebrew: ביבס) family from the Nir Ozkibbutz: 9-month-old Kfir (Hebrew: כפיר), 4-year-old Ariel (Hebrew: אריאל), 32-year-old mother Shiri (Hebrew: שירי; née Silberman), and her 34-year-old husband Yarden (Hebrew: ירדן).[5][6] The youngest child, baby Kfir, was the youngest hostage taken in the 7 October 2023 attacks.[7] Shiri's parents, who also lived on the kibbutz, were later found murdered.[8]
Amidst widespread concern and a campaign for their release, the Israeli Defense Forces (IDF) said that Hamas transferred the family to a different Palestinian terror group within Gaza, the Mujahideen Brigades of the Palestinian Mujahideen Movement.[9] Efforts to release Shiri and her children during a ceasefire between Israel and Hamas were unsuccessful; Hamas later claimed that they were killed as a result of an Israeli airstrike in Khan Yunis.[citation needed]
On 19 February, the IDF presented the relatives of the Bibas family a video showing Shiri and the children while they were still alive several days after the abduction. The video was apparently filmed in southern Gaza.[10]
