Political prisoners in Saudi Arabia are said to be suffering from malnutrition, cuts, bruises and burns, according to leaked medical reports that are understood to have been prepared for the country's ruler, King Salman. The reports seem to provide the first documented evidence from within the heart of the royal court that political prisoners are facing severe physical abuse, despite the government's denials that men and women in custody are being tortured. The Guardian has been told the medical reports will be given to King Salman along with recommendations that are said to include a potential pardon for all the prisoners, or at least early release for those with serious health problems. Pressure on Saudi Arabia over the detention and treatment of political prisoners has been growing in recent months amid claims that some female activists have been subjected to electric shocks and lashings in custody. With the kingdom also reeling from the aftermath of the murder of the dissident journalist Jamal Khashoggi, King Salman is said to have ordered a review of the decision to arrest and detain about 200 men and women in a crackdown ordered by his heir, Crown Prince Mohammed bin Salman. According to the medical reports seen by the Guardian, the comments about the detainees suggest many have been severely ill-treated and have a range of health problems. In almost all cases, the reports demanded the prisoners be urgently transferred from solitary confinement to a medical centre.
