Eight of the 26 hostages still to be released from Gaza during the first phase of the Israel-Hamas ceasefire are dead, The Telegraph has learned.

The Palestinian Islamist group Hamas has handed over to mediators a list showing that 25 Israeli hostages are still alive, out of 33 scheduled for release, an official of the group told Reuters on Monday.

Hamas will release more Israeli hostages this week, officials said Monday, including Agam Berger, who was not released along with four of her colleagues on Saturday.
