On Tuesday morning a fight broke between Tatars representing Muslim Religious Associations (MZR) and supporters of imam Nizar Charif, Salafists and converts. Several police vehicles were directed to the mosque.

The background of the dispute is control over the mosque belonging to MZR, the oldest Polish Muslim organization established by Tatar minority, fully integrated into Polish society.
