The US has warned Russia there will be “consequences” if the opposition activist Alexei Navalny dies in jail, writes BBC.

The UK, France, Germany and the European Union have also expressed their concern over his treatment.

Navalny’s doctors say he “will die within the next few days” if not given urgent medical attention for acute back pain and leg numbness.

Russia’s ambassador to the UK has said that Navalny is attention seeking and “will not be allowed to die in prison”.
