Putin critic Navalny moved to prison hospital after three weeks on hunger strike

Lawyers for the Russian opposition leader Alexei Navalny say his health is deteriorating, despite being transferred to a prison hospital earlier today.

Mr Navalny is 20 days into a hunger strike and is being denied access to his own doctors.

The US has warned Moscow of serious repercussions if he should die in jail. Tensions between Moscow and the West are at a new high after Russia moved more than 150,000 troops to the Ukrainian border and following a diplomatic spat between Russia and the Czech Republic.
