Iranian security forces attacked a gathering of dervishes in the central city of Isfahan on February 19, RFE/RL reports.
The dervishes had gathered next to the tomb of the great dervish poet Naser Ali when they were attacked.
The attack comes a day after the local authorities demolished
the house of worship of the Gonabadi dervishes in Isfahan.
A witness told RFE/RL that security officials used force and tear gas against the dervishes, a number of whom were injured and several were reportedly detained.
Dervishes are practitioners of Sufi Islam, and traditionally considered by Muslims as a source of wisdom, medicine, poetry, and enlightenment.
But many conservative Muslims consider them a danger to mainstream Islam.
