A crowd of several hundred people has begun storming the Ukrainian presidential administration’s office, a TASS correspondent reports from the scene.

Protest demonstrators have penetrated the first cordon of the National Guards and are trying to make their way to the conference hall. Police forces are being moved in. National guards in full riot gear entered a brawl with the demonstrators, who are demanding access to TV cameras for a statement.

Earlier, demonstrators demanded the introduction of martial law and resignation of all top law enforcement officials, including the defense minister and prosecutor-general.

Also, one of their demands is the removal of the 25th Kievan Rus battalion of the Ukrainian armed forces from the area of Debaltsevo. Women from the Mothers’ Union have told TASS their sons could not have been contacted for the past several days.
