Protesters in Iran called on Sunday for a three-day strike this week, stepping up pressure on authorities after the public prosecutor said the morality police, whose detention of a young woman triggered months of protests, had been shut down.

There was no confirmation of the closure from the Interior Ministry which is in charge of the morality police, and Iranian state media said Public Prosecutor Mohammad Jafar Montazeri was not responsible for overseeing the force.

Top Iranian officials have repeatedly said Tehran would not change the Islamic Republic's mandatory hijab policy, which requires women to dress modestly and wear headscarves, despite 11 weeks of protests against strict Islamic regulations.
