Who are the hostages freed by Hamas as part of the ceasefire in Gaza?

Three Israeli civilians, Sagui Dekel Chen, Iair Horn, and Alexander (Sasha) Troufanov, were released by militants from Gaza after being held for over 16 months. This release is part of a ceasefire deal between Israel and Hamas, which has already seen the release of multiple hostages and aims to free more captives in exchange for Palestinian prisoners.
