MOSCOW. May 5 (Interfax) - Police officers will stop any attempt by organizers of 'marches of dissent' to stage unauthorized protest actions.

"Any action that is not sanctioned by the city authorities will be foiled in strict compliance with the Russian legislation, and adequate measures of influence will be exerted on trespassers," a source with law enforcement agencies told Interfax.

The Other Russia opposition movement stated a day earlier that it intends to stage a 'march of dissent' in Moscow on May 6, despite the city authorities not sanctioning the march.

"The application for the action was filed on April 21. The mayor's office refused to authorize the action. It gave its reply eight days after the notification about the 'march of dissent'. And secondly, the officials did not propose any alternative venue for the procession," a report released on May 4 by the movement's press service says.

"The organizers have fully performed the duty of notifying the authorities in time, did not get any refusal by April 24 and, therefore, have the right to hold the public events they announced," the press service says.

The source also said that a number of authorized public actions will take place in Moscow on the day.
