On 25 August, several soccer fans were detained before and after the Tabriz derby match between Tractor Sazi F.C. and Shahrdari Tabriz F.C. for shouting slogans in favor of protecting the lake, including “Urmia Lake is dying, the Majlis orders its execution”.Further demonstrations took place in the streets of Tabriz and Urmia on 27 August and 3 September 2011. Amateur video from these events showed riot police on motorcycles attacking apparently peaceful protesters.According to the governor of West Azerbaijan, at least 60 supporters of the lake were arrested in Urmia, and dozens in Tabriz, because they had not applied for a permit to organize a demonstration.
