There will be blood — much more of it, if need be — was the implicit message from Ayatollah Khamenei at Friday prayers in Tehran. “Struggling on the streets after elections is not acceptable,” the Iranian Supreme Leader said. “If they do not stop these actions, then any consequences will be their responsibility.”

Khamenei emphasized that the Islamic republic would never “commit treason” by manipulating votes, that the country’s legal system does not allow vote-rigging. Mahmoud Ahmadinejad’s large margin of victory — supposedly by 11 million votes — proved that the election could not have been fixed, Khamenei said.

Many Iranians, and people around the world, understand that’s a lie. As Stanford University’s Abbas Milani noted on CNN Thursday night, numerous towns across Iran had reported vote totals for Ahmadinejad amounting to more than 100 percent of their resident populations.

But in Iran the fist, not the facts, likely will prevail.

Neil MacFarquhar reports on the violence unleashed in Iranian cities at night since last Friday’s election, with the vigilante thugs known as Basijis beating, looting and sometimes gunning down protesters they tracked during the day. Says one Iranian exile who helped found the Revolutionary Guards during the 1979 Islamic revolution: “It is the special brigades of the Revolutionary Guards who right now, especially at night, trap young demonstrators and kill them.”

If mass protests continue, as seems almost certain, more violence will spill into broad daylight, whether or not any foreign media is left inside the country to document it.

UPDATE: The Times’ Lede blog has a source in Tehran describing the use of Twitter — apparently less instrumental in organizing street demonstrations, while “primarily being used to communicate with the outside world.”

Regarding prospects for greater violence and ultimate political outcome, Steve Clemons shares an interesting dispatch from “a well-connected Iranian internationalist” who has been in Tehran during the post-election unrest. The source describes witnessing young Mousavi supporters in the streets at night, fighting back by “hunting” Basijis. He describes them as agile “militia style” groups, including “a surprising number of girls.”
