Relief, joy, anger and trauma all spilled out as Hamas released a new round of hostages and Israel freed more Palestinians from its prisons.

It is believed that at least two of the six American hostages still held in Gaza are alive — Sagui Dekel-Chen, 35, who grew up in Bloomfield, Connecticut, and Edan Alexander, 19, from Tenafly, New Jersey. Four other Americans are believed to have been killed in captivity.

Three Israelis and five Thai nationals were freed earlier in what PM Benjamin Netanyahu called "shocking scenes".
