TEHRAN The Islamic Republic of Iran vehemently denounces the subversive attack on the Iranian Center in Cologne, in which a group of Iranian and Muslim residents in Germany were holding mourning ceremonies in commemoration of the martyrdom anniversary of the Third Imam of the Holy Prophet's Household Imam Hussein (AS). A group of the anti-revolutionary subverts attacked the attendants within the ceremonies, held at the Iranian Center, without facing solid resistance from the German police for their disregard of the religious sanctity of Muslims.
