An estimated 70,000 pro-Western Ukrainians thronged the heart of Kiev on Sunday vowing never to give up their drive to oust President Viktor Yanukovych for his alliance with old master Russia.

Ukrainian President Viktor Yanukovich returned to work on Monday after four days of sick leave, issuing a warning about rising "radicalism" after more than two months of unrest on the streets but giving no word on a new prime minister.

A leading Ukrainian opposition activist who vanished for eight days emerged bloodied and badly beaten on Friday, saying his captors cut off an ear and drove nails through his hands before dumping him in a forest.
