Israel has released footage claiming to show prisoner without bandages
The Israel Prison Service says Mohammed had been examined by a medic before leaving prison, with no medical problem diagnosed.
The video shows the teenagers' hands unbandaged - but they are out of shot for most of the video. The prison service claims the footage proves his allegations are false.
X-Rays taken from Palestinian doctors in Ramallah were shown to two doctors in the UK, who confirmed that they showed fractures in both of Mohammed's hands.
