Trump hints at 'action' if Hamas doesn't return hostage bodies

Israeli officials on Tuesday confirmed the deaths of two hostages whose remains were returned to Israel on Monday.

The remains of Guy Iluz and Bipin Joshi were among the four deceased hostages who were transferred back to Israel on Tuesday, the Israel Defense Forces said on social media.

The names of the two others whose remains were transferred had not yet been "cleared for publication," the IDF said.

Joshi, a Nepalese agriculture student who was in Israel to study, was one of two hostages previously thought to be alive following the Oct. 7, 2023, attack by Hamas, according to Israeli officials.

Joshi's name had not been included in the list of 20 living hostages published by Hamas. He was 23 when he was abducted, the IDF said.

"It is assessed that he was murdered in captivity during the first months of the war," the IDF said on Tuesday.

Iluz was "abducted alive and injured by Hamas after escaping the Nova music festival," the IDF said.

"Guy died from his wounds after not receiving proper medical treatment while held captive. He was 26 years old at his death," the IDF said on Tuesday.

Former President Joe Biden commended President Donald Trump and his administration's work getting the ceasefire agreement "over the finish line."

"The road to this deal was not easy," Biden said on social media. "My Administration worked relentlessly to bring hostages home, get relief to Palestinian civilians, and end the war. I commend President Trump and his team for their work to get a renewed ceasefire deal over the finish line."

Biden also expressed his hope that the Middle East is on a path to enduring peace and "a future for Israelis and Palestinians alike with equal measures of peace, dignity, and safety."

Egyptian President Abdel Fattah El-Sisi has awarded the Nile Collar -- Egypt's highest state honor -- to President Donald Trump for “his significant contributions to promoting peace, resolving conflicts, and most recently, his pivotal role in ending the war in Gaza,” El-Sisi’s office said in a statement.

At Monday's peace summit, El-Sisi said the award is presented “in recognition of President Trump’s efforts” and is typically reserved for heads of state who provide “distinguished services to humanity.”
