KIEV, Dec. 20 - Ukraine's Femen group which specializes in topless protests in public raised an SOS Tuesday over three activists who it said were seized by police in Belarus, forced to strip, threatened with violence and then abandoned naked in woodland.

The Kiev-based group said the three were seized by police in the Belarusian capital Minsk on Monday after staging a typical bare-breasted protest on the steps of the KGB state security headquarters, mocking authoritarian President Alexander Lukashenko.
