Sky News can reveal new information about the death of one of Gaza's best-known doctors - who died earlier this year while in Israeli prison. Testimony from an inmate at the prison where Dr Adnan Al-Bursh died has detailed claims about the moments leading up to his death. The surgeon documented the early months of the war between Hamas and Israel on his phone as he continued to work in northern Gaza before being detained by Israeli forces. Sky's John Sparks has been speaking to those who saw him in his final days. The Israel Defence Forces say Dr Adnan Al-Bursh "did not die under the responsibility of the IDF". The Israel Prison Service says "no such events have occurred under IPS responsibility."
