The doctors of Russian opposition politician Alexei Navalny are still not allowed to see him; it was posted on Twitter by Head of the "Alliance of Doctors" Anastasia Vasilyeva.
Doctors stood in front of the colony for two hours but in vain.
Alexei Navalny's health condition deteriorated.
Vasilyeva says Navalny may die in a few days without treatment.
Navalny's blood test indicates kidney failure and heart problems.
Since March 31, the oppositionist has been on a hunger strike.
