The first hostages freed from Gaza under a long-awaited ceasefire agreement are back in Israel. The news sparked jubilant scenes in Tel Aviv where large crowds gathered for news of their release.

The three freed Israeli hostages – the first of 33 to be released over the next six weeks – are Romi Gonen, Doron Steinbrecher and Emily Damari. In exchange, 90 Palestinian prisoners and detainees will also be released.

The Israeli military withdrew from several locations in southern and northern Gaza after the truce began earlier on Sunday, an Israeli military official told CNN.

Displaced Gazans have started returning to their homes, while the aid trucks laden with much-needed supplies have crossed into Gaza. Here’s what we know about how the ceasefire deal will work.
