This past week marked the 30th anniversary of the taking of the U.S. embassy in Tehran. Traditional massive demonstrations against “The Great Satan” turned into massive demonstrations by people still upset by the results of the last elections.
The first set of pictures that came out of the demonstrations were from Twitter and other mobile phone services.
The leadership in Tehran does not want anyone seeing these demonstrations. So instead of addressing the issues raised by the demonstrators, the government is trying the same tactic dictators (See China, Cuba, Vietnam, etc.) have long tried: Silence the messengers.
Here is a story from The Times: Foreign journalists arrested as Iran restricts reports on opposition.
