Hamas accused Israel on Friday of breaching their ceasefire accord and it delayed announcing the names of three more Israeli hostages due to be exchanged for Palestinian prisoners in the latest stage in a fragile deal aimed at ending the war in Gaza.

Hamas identified the three Israeli hostages that it plans to free in the next release mandated by the fragile ceasefire agreement, a sign the deal was moving forward Friday even as U.S. and Israeli officials continued calls to relocate Gaza's population after the war.

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.
