IslamNews – Doctors for the jailed Russian opposition activist Alexei Navalny say he “will die within the next few days” if not given medical attention.
Doctors say recent blood test results indicate he could suffer cardiac arrest or kidney failure at any moment.
Navalny has been on a hunger strike for 19 days, to demand proper treatment for acute back pain and leg numbness.
The Russian ambassador to the UK has said that Mr Navalny will not be allowed to die in prison.
A prominent critic of President Vladimir Putin, Mr Navalny was jailed in February for old embezzlement charges.
Four doctors, including his personal physician, Anastasia Vasilyeva, have written to prison officials to ask for permission to see him urgently.
In the letter, which Dr Vasilyeva posted on Twitter, the experts said Alexei Navalny’s potassium had reached “critical levels”.
“This means both impaired renal function and that serious heart rhythm problems can happen any minute,” it explained.
