The BBC reports that Iran has resorted to satellite jamming to block some of its newscasts from Tehran, where thousands poured into the streets over the weekend after it became clear that incumbent President Mahmoud Ahmadinejad was claiming a victory in Friday elections. This video is interesting on several counts. It contradicts reports from other news outlets (including AP) that there was “no sign of violence or challenges from security forces. Anti-riot stood by with their helmets off and shields at their sides.” It also contradicts reports that post-election anger rests only with university students. Note the older men also involved in skirmishes with Iranian police.

Street protests and violence continue at this hour, with supporters of lead opposition candidate Mir Hossein Mousavi saying they won’t back down in calling for a recount.

UPDATE: It’s night time in Tehran and here’s the latest feed from the BBC, taken after the television crew was arrested and had some of its tapes confiscated.

“Nothing has been seen upon the streets of Tehran like this since the revolution right back in 1979,” said the BBC’s John Simpson, with chants behind him of “We want freedom, we want freedom” ringing.
