Great Britain sanctions the leaders of the prison where Navalny died

Great Britain has frozen the assets of six leaders of the Arctic prison where opposition leader Alexei Navalny died on Friday, the BBC writes.

Sanctioned individuals have also been banned from traveling to Britain.

Western leaders say Russian authorities, including President Putin, are to blame for Navalny's death.

But this has been denied by the Kremlin.

Russian authorities have refused to give Navalny's body to the family. They gave little and contradictory information about his death.

The British government has also demanded that Navalny's body be immediately released to his family and that a full and transparent investigation be carried out.

The appeal from Britain echoes similar calls from Navalny's mother, who was filmed on Tuesday outside the prison where he died saying she had been trying for five days to see her son's body but didn't even know where it was.
