Russian opposition leader Alexey Navalny missing from prison, says his team

Lawyers for Alexey Navalny said Monday they have lost contact with the jailed Russian opposition leader, who was believed to be imprisoned in a penal colony about 150 miles east of Moscow, and his whereabouts are unknown.

Navalny was sentenced to 19 years in prison in August, after he was found guilty of creating an extremist community, financing extremist activities and numerous other crimes. He was already serving sentences of 11-and-a-half years in a maximum security facility on fraud and other charges he denies.

Supporters of Navalny claim his arrest and incarceration are a politically motivated attempt to stifle his criticism of Russian President Vladimir Putin.
