Hamas has said four more female Israeli hostages will be freed this weekend in return for Palestinian prisoners, as the new US president, Donald Trump, said he was not confident that the ceasefire deal that he personally insisted on would hold.

The next group of hostages due to be released is expected to include captured female Israeli soldiers, who will be exchanged for Palestinian prisoners serving more lengthy sentences who are being held in Israeli jails, some of whom will be deported to third countries.
