Up to 150 people were taken captive when Hamas launched its surprise attack on 7 October, Israel said. Hamas has said it has hidden them in "safe places and tunnels" within Gaza, and threatened to kill hostages if civilian homes are bombed by Israel without warning.

These are the stories of people confirmed by the BBC, or credibly reported, to have been taken hostage by Hamas from Israel. They include 13 children and at least eight over-60s.

Liri Elbag, 18, had just started military training as an Army lookout near the Gaza border when Hamas attacked, her father Eli told the Associated Press.

Roni Eshel, 19, was based in an army base on the Gaza border. Her family say that the last time they heard from her was on Saturday morning. Her base was under attack. She sent a text message to her mother at around 09:30, saying: "Mom, I am okay, I am busy, I love you."

Almost two days later, the Israeli army informed the family that both Maya and Itay had been abducted.

The parents of Sharone Lifschitz - a London-based artist, who asked for them not to be identified for fear of reprisals - are believed to have been taken hostage from Nir Oz, a kibbutz about 400m from the border with Gaza. Ms Lifschitz said her father speaks Arabic and spent his time in retirement driving Palestinians who needed medical treatment to hospital.

Ada Sagi, 74, is also believed to have been abducted from her home in Nir Oz. Her son, Noam, said Israeli soldiers found bloodstains but no sign of his mother and she was not among those killed or injured in the small community.
