RFE/RL brings this report and video from Moscow’s weekend rallly and concert, organized by Khimki forest activists. Uncharacteristically, the event received permission from city officials. But the permission was revoked at the last minute. When authrities prevented the use of sound equipment, the rally took on increasingly political dimensions:

The roughly 2,000 people who showed up were met with the usual heavy police presence, with officers in riot gear and police vehicles surrounding the square. Those attending the rally were forced to stand in long lines to pass through metal detectors.
