The largest anti-government protests in Iran since 2009 gathered strength on Sunday, spreading to as many as 80 cities, even as the authorities escalated a crackdown that has reportedly killed 41 people and brought the arrests of prominent activists and journalists.

News from Iran has trickled out with many hours of delay.
