American-Israeli Keith Siegel and two other hostages being held in Gaza were released to the Red Cross by Hamas in part of the ceasefire agreement between Israel and Hamas. Siegel’s release marks the first American to be released since the ceasefire agreement was reached last month.

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.
