The women lost their appeal in court earlier this month
Two convicted women from the Russian punk band Pussy Riot are on their way to two prison camps far from home, their lawyers and supporters say.
Conditions are reported to be tough at the camps, in Perm and Mordovia, east of Moscow. Those areas were used for mass prison colonies in the Soviet era.
Maria Alyokhina, 24, and Nadezhda Tolokonnikova, 22, were jailed for two years each in August for singing a crude anti-Kremlin song in a cathedral.
The jail sentence was widely condemned.
They were convicted of "hooliganism motivated by religious hatred" over the obscenity-laced "punk prayer" they performed in Moscow's main cathedral, Christ the Saviour, on 21 February.
Two lawyers and activists in the protest group Voina reported the young women's transfer to the camps, far to the east of Moscow, on Monday. Tolokonnikova's husband Pyotr Verzilov is a member of Voina.
On Twitter the Pussy Riot group said on Monday: "At the weekend Nadya [Tolokonnikova] was sent on a special flight to Mordovia, while Masha [Alyokhina] was sent to Perm region.
Those are cruellest camps of any that could have been chosen."
Comment: Right, so the BBC is going to investigate itself?
They have no other choice than to try and keep a lid on things, of course. The alternative is to lift the lid on the inter-connected pedophile networks that control the world.
