"The detention of 400 protestors in New York means a top challenge for American democracy," member of the parliament's National Security and Foreign Policy Commission Mehdi Mehdizadeh told FNA on Sunday.
"As soon as Americans find the interests of the capitalist system in danger, they prepare to suppress even their own people in its worst possible manner, and this is a point which was manifested in the recent detentions in New York," he added.
Mehdizadeh reiterated that the liberal democracy system has lost its credit among the American people and they no more trust in the liberal culture.
