On October 28. three men interrupted LGBT issued film screening in the headquarters of Political Critique organisation in Warsaw. One of them fired smoke grenade, shouting “bomb!”. Panic broke out. In a caustic smoke about 40-50 people were trying to run out of the room. The second grenade was installed in the stairwell in order to impede the evacuation of participants of the screening session. The incident ended happily. No one was hurt. Police are searching for the perpetrators of the attack. All eyes are directed towards Polish nationalists whose strength in the recent years has been rapidly growing.
