Dozens of celebrities in the American entertainment industry signed a joint letter published Tuesday early morning, in which they thanked US President Joe Biden for his part in the release of the four abductees - and demanded the release of all the abductees held in Gaza. The letter, which launched a campaign called #NoHostageLeftBehind, was shared on their official social media accounts.

"Dear President Biden," they wrote in the letter, "We are heartened by Friday’s release of the two American hostages, Judith Ranaan and her daughter Natalie Ranaan and by today’s release of two Israelis, Nurit Cooper and Yocheved Lifshitz, whose husbands remain in captivity. But our relief is tempered by our overwhelming concern that 220 innocent people, including 30 children, remain captive by terrorists, threatened with torture and death. They were taken by Hamas in the savage massacre of October 7, where over 1,400 Israelis were slaughtered - women raped, families burned alive, and infants beheaded."

"Thank you for your unshakable moral conviction, leadership, and support for the Jewish people, who have been terrorized by Hamas since the group’s founding over 35 years ago, and for the Palestinians, who have also been terrorized, oppressed, and victimized by Hamas for the last 17 years that the group has been governing Gaza. We all want the same thing: Freedom for Israelis and Palestinians to live side by side in peace. Freedom from the brutal violence spread by Hamas. And most urgently, in this moment, freedom for the hostages.

"We urge everyone to not rest until all hostages are released. No hostage can be left behind. Whether American, Argentinian, Australian, Azerbaijani, Brazilian, British, Canadian, Chilean, Chinese, Danish, Dutch, Eritrean, Filipino, French, German, Indian, Israeli, Italian, Kazakh, Mexican, Panamanian, Paraguayan, Peruvian, Polish, Portuguese, Romanian, Russian, South African, Spanish, Sri Lankan, Thai, Ukrainian, Uzbekistani or otherwise, we need to bring them home."

Last weekend, 58 other celebrities published an open letter demanding that Biden call for a ceasefire in Gaza and Israel. Among the signatories of the letter were Oscar winners Joaquin Phoenix, Cate Blanchett, Susan Sarandon and Marcella Ali, comedian Jon Stewart and actors Kristen Stewart and Riz Ahmed. The letter included an afterword from UNICEF spokesman James Elder, who noted "the devastation caused to the Gaza population by the Israeli Air Force attacks and the reduction of water and electricity supplies to the Strip."
