Israel has released 369 Palestinian prisoners and detainees in the latest exchange for Israeli hostages captured by Hamas as the fragile ceasefire hold.

Hamas-led militants released three gaunt, frail-looking Israeli hostages and Israel freed nearly 200 Palestinian prisoners Saturday in the latest exchange of a ceasefire agreement that has paused 16 months of war in Gaza.

Over 580 terrorists have been released in the first four waves of the deal's first phase, with another 200 expected to be released over the course of the deal.
