During the 7 October 2023 attacks, part of the broader Gaza war, the Israeli-Argentinian/Peruvian[2][3][4]Bibas (Hebrew: בִּיבָּס) family was kidnapped by Palestinian militants from their home in kibbutzNir Oz, and held hostage in the Gaza Strip. The family comprised 34-year-old Yarden (Hebrew: יַרְדֵּן), his 32-year-old wife Shiri (Hebrew: שִׁירִי; née Silberman) and their two sons Ariel (Hebrew: אֲרִיאֵל) and Kfir (Hebrew: כְּפִיר), aged 4 years and 9 months respectively.[5][6] Kfir was the youngest hostage taken from Israel on 7 October. Yarden was abducted separately from his wife and children.[7]
In late 2023, Hamas claimed that Shiri, Ariel, and Kfir had been killed during the Israeli bombardment of Gaza.[8] Israel did not confirm their deaths, but expressed grave concerns over their welfare.[9][10] As part of the Gaza war ceasefire and prisoners exchange, Yarden was released alive on 1 February 2025.[11] On 18 February 2025, Hamas announced that it would release the bodies of Shiri, Ariel, and Kfir,[12][13] and said it handed over their bodies on 20 February.[14] Israel confirmed the bodies of Ariel and Kfir had been handed over, but said the body marked as that of Shiri was of an unidentified person.[15]
Prior to the attack the family had considered moving to the Golan Heights, tired of living in constant fear and being bombarded by Gazan rockets.[7]
On the day of the attack, Yarden Bibas texted his sister to update her on the fighting at and around the Nir Oz Kibbutz.[16] At around 6:30 am, he sent her an update which included rocket fire, and then that the militants had entered the kibbutz with concern that his children did not know how to keep quiet. By about 9:45, he sent "They're in" shortly after having sent "I love you" to his family.[7] Yarden had reportedly first believed that the rocket fire was "just another bombing" and had hesitated to use the gun in the home due to the number of militants with automatic weapons.[17]
At some point during the attack Yarden Bibas left the family's safe room, reportedly to distract the militants and attempt to save his wife and children. Yarden was then captured separately from the rest of his family.[18]
Multiple pieces of media of the family were circulated online, such as a video of Shiri holding her redheaded children in her arms, with a look of terror on her face as she was surrounded by militants. Multiple pictures found later showed Yarden, on the day of the attack, bleeding from the head, and being herded away by gunmen.[7][19]
Shiri's father José Luis (Yossi) Silberman, and his wife, Margit Shnaider Silberman, were also presumed to be missing from the kibbutz. Margit Shnaider Silberman moved to Israel from Peru in the 1970s. José Luis (Yossi) Silberman was originally from Argentina, both Silbermans were in their 60s. The Silbermans were later found dead and officially identified as deceased on 21 October.[20][19][21]
Israel said the family was kidnapped by the Palestinian group called "Lords of the desert".[22] Israel expressed concern that Shiri and the children had been transferred to a different armed group within Gaza, the Mujahideen Brigades of the Palestinian Mujahideen Movement.[23]
On 29 November 2023, Hamas' armed wing, the Al Qassam Brigades, said Shiri and her children had been killed in Israeli bombing of Gaza.[24] Israel said that Hamas' claims were not verified, and warned they could be part of their psychological warfare.[25][26][27] IDF chief spokesperson said, regarding the family's location, that the IDF did not believe the boys and their mother were in the hands of Hamas[25] but they had consistently refused to name any other group, saying only "another group".[27] After Yarden Bibas's release the group was identified as the Kataib Mujahadin.[28]
In September 2024, a freed hostage claimed to have seen Yarden Bibas and Ofer Kalderon, both hostages from the Nir Or kibbutz in cages while she was in a tunnel under the Gaza Strip. The women stated that she was able to speak with both men during her time there, and the men were released from the cages hours at a time to speak with her.[29]
When Yarden Bibas was released, he had lost 15 kilograms (33 lb). He reportedly told Israeli authorities that he was starved, with some days not given any food. Yarden's captivity coincided with Israeli blockade of humanitarian supplies into Gaza and the Gaza Strip famine.[30][31] Most of the time he was held in isolation in an underground cell, rarely seeing sunlight. He was allowed to meet other hostages only during meals. He requested to be held with an old friend that he came across during his time in captivity, but his request was denied. He also reportedly said that he was dressed in a galabeya.[18]
Yarden Bidas reportedly asked his captors on numerous occasions about his family. In one instance his captors told Bibas that his family had evaded capture and were spotted in Tel Aviv. In another case, his captors demanded a female hostage tell him that his family died. After the female hostage refused, the captors demanded a male hostage tell him that his family died. Hamas filmed Yarden breaking down upon hearing the fate of his family, and criticizing Israeli Prime MinisterBenjamin Netanyahu.[18][32]

On 7 October 2023, the deputy chief of Hamas, Saleh al-Arouri said that Palestinians had abducted Israelis so they could force Israel to release thousands of Palestinians (including 200 women and children) in Israeli custody.[33][34] On October 9, Hamas offered to release all civilian hostages in exchange for Israeli army not entering Gaza, but the Israeli government rejected the offer.[35] On 17 October 2023, a Hamas official said it would release all civilian (but not military) hostages in exchange for Israel ending the bombing of the Gaza Strip.[36] On 19 October, Human Rights Watch criticized Hamas for conditioning the release of Israelis upon Israel's release of Palestinians, arguing "civilians, including children...should never be treated as bargaining chips."[37]
On 22 November 2023, Israel agreed to release 150 Palestinian women and children, in exchange for Hamas agreeing to release 50 Israeli women and children.[38] Shiri and her children were expected to be released, but were not released. On 29 November, Hamas' armed wing, the Al Qassam Brigades, said Shiri and her children had been killed in Israeli bombing of Gaza.[39] On 1 December, Israel considered it a violation of the framework that they were not released.[40] After the brothers were not freed during the temporary ceasefire, their relatives launched a campaign demanding their release.[19]
On 1 December, 2023, Hamas offered to release the bodies of Shiri, Kfir and Ariel.[41] This offer was also confirmed by Israeli officials and Arab diplomats.[42] Israel refused, demanding that living female hostages be returned before the dead bodies.[42] On the same day, Hamas also clarified that Shiri, Kfir and Ariel had been killed by Israeli airstrikes before the truce went into effect.[41] The IDF responded that "Hamas is wholly responsible for the security of all hostages".[41]
A cousin of the Bibas family raised a request to speak with US President Joe Biden, Egyptian President Abdel Fattah El-Sisi and Qatar's Emir Tamim bin Hamad Al Thani, to petition them to help in the release of the family. He also mentioned that they were working with the Argentinian government to help petition for the release of the family.[3] In early December 2023 per Foreign Minister Eli Cohen, all Israeli embassies and consulates either lit their buildings in orange or displayed images of the family. The display was supposed to coincide with the first lighting of Hanukkah candles.[43]
Around Kfir Bibas' first birthday in January 2024, family members celebrated his (18 January) birthday and raised awareness for the family still reportedly held as hostages. Hundreds of people gathered at the Hostages Square in Tel Aviv to celebrate Kfir and his family with a performance by Israeli children's music stars and wore orange to symbolize the two children's hair.[44] Kfir's picture was also seen next to Israeli President Isaac Herzog while he spoke at the World Economic Forum that same week.[45] On 19 February, the Israeli military released a video which purportedly showed members of the Bibas family in the Khan Younis area.[46]
In August 2024, during the Redhead Days Festival in Tilburg, Netherlands which is known for celebrating people with auburn-hair, members of the Bibas family urged participants to spotlight the Bibas children and to raise awareness about their continued time as hostages.[47]
In January 2025, during the 2025 Gaza war ceasefire and prisoner exchange, before it was announced that Yarden Bibas would be included in the exchange, a group supporting the family asked for the public to wear orange in honor of the family.[48] Israeli officials had asked that Hamas provide more information on the condition of Shiri Bibas and the two children on January 29.[49]

On 31 January, Hamas announced that they were going to release Yarden Bibas on February 1, as part of the fourth round of releases of the ceasefire and prisoner exchange agreement. The status of Yarden Bibas's family, Shiri, Ariel and Kfir was not clear at the time of his release and they were not included in earlier releases which were supposed to prioritize living women and children.[50] At the time of the ceasefire and prior release of other hostages, the Bibas children were the only Israeli children still held, while Shiri is the only Israeli woman still held.[51]
On February 20, Hamas released four bodies: purportedly of Ariel, Kfir, Shiri, and a fourth hostage, Oded Lifshitz, who was also been kidnapped during the Nir Oz attack.[52][53][54] The four bodies were taken to Israel's forensic institute for identification of the deceased.[55] While Israel was able to forensically confirm the bodies of Ariel, Kfir, and Lifshitz, the fourth body did not belong to Shiri, nor any other Israeli hostage held by Hamas.[56] Hamas had announced in November 2023 that Shiri, Ariel and Kfir were killed as a result of Israeli bombings in November 2023. On 20 February 2025, Israel said that forensic evidence showed that the children were "brutally murdered" in November 2023.[8][56]
The handover was performed as a two-step process, with the first step being a handover of coffins from Hamas to the Red Cross, with the handover from the Red Cross to the IDF performed in a second step. In the first step, the four coffins were brought to a stage in Khan Younis wrapped in black with labels bearing the deceased names and pictures, and placed in front of a poster bearing the image of Netanyahu as a vampire with the four deceased superimposed. The poster blamed Netanyahu and Israel for their deaths, and denounced Israel with spent Israeli munitions displayed on the stage near the coffins. In the second step, a rabbi conducted a ceremony upon receipt of the coffins and they were transported into Israel draped in Israeli flags. Israeli citizens lined the roads near the Gaza border to watch the convoy and pay their respects, as well as gathering in Hostages Square.[57][58]
The coffins were provided to Israel locked, without keys.[59] Upon opening the coffins, investigators discovered Hamas propaganda, which Israel considered "a desecration of the sanctity of the dead". Israel therefore filed a complaint with Egypt, Qatar and the United States who helped negotiate the ceasefire agreement between Israel and Hamas.[60]
After Yarden was released, the Bibas family issued a statement that "a quarter of our heart has returned.....but the home remains incomplete".[61] His family also thanked the Israeli public for its support and concern, and that while he had lost a significant amount of weight he was in good spirits and physically stable.[62]
After the release of the bodies of Shiri, Ariel and Kfir multiple individuals spoke out. Israeli president Isaac Herzog issued a statement stating that the "hearts of an entire nation line in tatters" and spoke directly to the deceased stating that he bowed his head and asked for forgiveness in not protecting them or bringing them home safe.[57]
Argentine President Javier Milei declared a national day of mourning in Argentina following the return of the bodies, as the Bibas children held Argentine citizenship. Sabrina Ajmechet, President of the Argentinian Commission for Human Rights, wrote: "Two Argentinian babies assassinated because of Hamas terrorism. I hope that never again, after this, I have to hear that what happens in Israel and Gaza is not our concern, of all Argentines".[63]
