Critics say Putin's Olympic security decree violates rights

MOSCOW (Reuters) - Russian President Vladimir Putin has signed a decree to tighten security in the Black Sea resort of Sochi during the 2014 Winter Olympics, imposing restrictions on freedom of movement and assembly that critics said violated human rights.

The decree creates a "prohibited zone" encompassing much of the sprawling city, barring travel into Sochi by road without special permission and banning public gatherings "not connected" with the Olympics in high security areas on land and sea.
