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.

Hamas announced dual U.S.-Israeli citizen Keith Siegel is one of three hostages to be released Saturday as part of the initial phase of its cease-fire and hostage-prisoner exchange agreement with Israel.
