Iranian authorities have imposed a virtual information blockade after opposition leaders issued a call for supporters to take to the streets during an important government anniversary on Thursday, people inside the country are saying.
Residents of the Iranian capital said Wednesday that text messages on many messaging services have been blocked and Internet speeds have slowed to a crawl.
The Internet "comes on only a few minutes each day, but you never know when," one Iranian wrote in an e-mail to CNN, which he said took seven hours to send. "This has been going on for more than four days now. I contacted my Internet provider and they said it is out of their control."
