In an elaborate move, Hamas gunmen handed four hostages over to a waiting Red Cross vehicle.
Soldiers Daniela Gilboa, Naama Levy and Karina Ariev, all 20, and 19-year-old Liri Elbag were taken from a military base on the Israel-Gaza border in an attack on 7 October.
It is the second part of a series of Israeli hostage releases and Palestinian prisoner exchanges since a ceasefire was reached earlier this month.
