Israel had been preventing vast crowds of Palestinians from using a coastal road to return to northern Gaza, accusing Hamas of violating the truce agreement by failing to release civilian women hostages.
As the ceasefire took effect on Sunday morning, thousands of displaced, war-weary Palestinians set off across the devastated Gaza Strip to return home.
Israeli Prime Minister Benjamin Netanyahu said the deal's final details were still being worked on, but he thanked Biden for "promoting" it. Hamas leader Khalil al-Hayya said it was the result of Palestinian "resilience".
Officials from mediators Qatar, Egypt and the US as well as Israel and Hamas said an agreement for a truce in the besieged enclave and release of hostages was closer than ever.
Netanyahu is facing three cases where he is alleged to have used relationships with rich, powerful men for personal and political gain, including to influence media outlets they owned or controlled.
Dr. Adnan al-Bursh, a renowned Palestinian surgeon from Gaza, was brutally tortured and left to die in Israel's Ofer Prison, according to new details revealed by a Sky News investigation. His death highlights severe abuses faced by Palestinian detainees amidst ongoing Israeli operations.
