"Iranian police have placed opposition leader Mir Hossein Mousavi under house arrest," the BBC reports, citing Mousavi's official website as its source. And the network adds that the website "says the move is intended to block him from attending a rally in Tehran in support of the protests in Egypt."
The Associated Press says that "security forces cut phone lines and blockaded the home of an Iranian opposition leader Monday in attempts to stop him attending a planned rally in support of Egypt's uprising, a reformist website reported. Iranian authorities have poured police and militiamen onto the streets of Tehran to challenge any pro-Egypt marches, which officials worry could turn into demonstrations against Iran's ruling system."
As for the rally, Reuters writes that "hundreds of Iranians marched toward a Tehran square on Monday in a banned rally supporting popular uprisings in Egypt and Tunisia, but their way was blocked by police and security forces, witnesses said."

Update at 11:30 a.m. ET. NBC News' Ali Arouzi reports from Tehran that the protests began at 10 a.m. local time, that a young girl "went out outside the Revolutionary Court [and] climbed on top of a big construction crane and was waving a green flag and holding up signs and pictures of protesters [who] had been arrested last year." Later, he said, "thousands of Iranians" took the streets.
"Crowds were beaten back [and] tear gas was used," Arouzi said, "and they're still out there right now ... defying a strict warning from the government." (Note: The NBC video includes scenes from Tehran on Friday, when people came out to celebrate the 32nd anniversary of Iran's Islamic Revolution. Those are not scenes from today.)

The two groups scuffled in front of the university and three people were injured, two from stones and one was stabbed a traditional Yemeni dagger."
