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 has delayed the naming of three hostages to be released on Saturday after accusing Israel of multiple breaches of the ceasefire agreement, alleging that it has delayed hundreds of humanitarian aid trucks and only allowed in a fraction of the tents needed to accommodate people who have lost their homes in the conflict.

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.
