Two Sufis have been reportedly arrested in Tehran and Shiraz.
Simin Nematollahi and Kasra Nouri are members of the Gonabadi Nematollahi order that have come under increasing pressure by Iranian authorities.
The Majzouban website, which covers news of the dervishes, reports that the two have been charged with spreading propaganda against the Iranian establishment.
In recent years, Iranian authorities have demolished several houses of worship of the dervishes and sentenced dozens of them to lashing and imprisonment.
