A group of environmental activists and representatives of Left Front tried to carry out an unauthorized rally for the Khimki Forest in front of the Kremlin. The activists were brutally detained by police and unknown men in civil clothes. They were left in a police station tonight, and released only next day.

Another action was calmer. A group of artists performed in the Khimki Forest to protest against the clearing.
