An Israeli-Russian woman held captive for two and a half years by militants in Iraq has told the BBC how she invented "confessions" to try to get her captors to stop torturing her.

Elizabeth Tsurkov, who was freed in September, says she suffered extreme abuse for 100 days, leaving her physically and mentally scarred.

"My health is not great," Ms Tsurkov says.

The interview she gave to BBC Newshour was conducted in central Israel, propped up on a bed. It is now almost three months after her release from captivity in Iraq, where she was held for 903 days. The first four and a half months had been particularly brutal: she was, she says, trussed and hung from the ceiling, whipped, sexually abused, electrocuted.
