Watch live as family members of British-Israeli Hamas hostages address the Israeli Embassy in London on Tuesday, 24 October.
The press conference comes as an 85-year-old grandmother whose daughter is based in London has been released from Hamas captivity.
Yocheved Lifshitz was released alongside fellow Israeli citizen Nurit Yitzhak, 79, on Monday evening.
Their husbands, aged 83 and 84, remain captive alongside more than 200 other civilians.
Ms Lifschitz's daughter Sharone Lifschitz, who spells her name differently to her mother, said the 85-year-old "seems OK" after her 16-day ordeal.
“She is very sharp and is very keen to share the information, pass on the information to families of other hostages she was with,” Sharone told the BBC.
"My mum said they had been looked after and there was a doctor there, so this gives a lot of comfort to everybody."
Speaking after her kidnap, Yocheved said she had been "through hell, that I could not have known."
