A prominent Ukrainian opposition activist who disappeared more than a week ago says he was abducted and tortured.

Dmytro Bulatov is the leader of opposition movement Automaidan that organises protest convoys. He says he was kidnapped, repeatedly beaten and hung up by his wrists.

Mr Bulatov, who is being treated in hospital, said he was dumped on the outskirts of the Ukrainian capital, Kiev, by men who spoke with Russian accents.
