Ninety Palestinian prisoners were released overnight as part of the first phase of the Gaza ceasefire, the Israeli prison service said.
Three Israeli women including a dual British national were earlier released by Hamas, they are being treated in a Tel Aviv hospital and are in a stable condition.
There have been emotional reunions on both sides - Palestinians were greeted with hugs and cheers by their families, while freed hostage Israeli Emily Damari shared the moving moment she had a video call with her family.
