The AP reports:
Hundreds of young men chanted "death to the dictator" and fled baton-wielding police in the capital Thursday as opposition activists sought to revive street protests despite authorities' vows to "smash" any new marches.Tehran governor Morteza Tamaddon warned that any new march Thursday would meet the same fate. "If some individuals plan to carry out any anti-security actions by listening to calls by counter-revolutionary networks, they will be smashed under the feet of our aware people," he said.
The NYT reports:
Security forces began clashing with protesters shortly after they began massing in the streets of Tehran on Thursday evening, as an initially festive demonstration quickly turned grim, witnesses said. Tear gas was fired into Lelah Park, they said, and a woman whose coat was covered in blood ran from Revolution Square, one of the main gathering spots during the initial weeks of protests over the June 12 election. She said that police officers were beating protesters.
[A]t the end of the work day, hundreds of protesters began packing the streets of one area of Tehran, chanting, clapping and sitting in jammed traffic as drivers honked their horns, witnesses said. Families brought their children. Many held a hand in the air in the defiant V for victory. The security forces quickly moved in. Reuters, citing witnesses, reported that the police used tear gas to disperse a group of about 250 protesters as they headed toward Tehran University, shouting support for [Mousavi].
[A] group of around 300 young people gathered in front of Tehran University and began to chant, "Death to the dictator," witnesses said. Many of them wore green surgical masks, the color of Mousavi's movement.
Police charged at them, swinging batons, but the protesters fled, then regrouped at another corner and resumed chanting, the witnesses said. Police chased them repeatedly as the protesters continued to regroup, the witnesses said, speaking on condition of anonymity because they feared government retribution.
Within an hour, the number of protesters grew to about 700 and marched toward the gates of Tehran University, the witnesses said. A line of policemen blocked their path, but they did nothing to disperse the gathering as the protesters stood and continued to chant, the witnesses said.
"Police used tear gas twice to disperse the crowd. There was also many Basij militia on motorbikes patrolling the area," said the witness, who asked not to be named. Another witness said police urged passers by through loudspeakers to leave the area.
MSNBC fail. As far as I can tell, there has been zero mention of the events in Iran thus far on MSNBC. CNN has been doing updates roughly every 30 minutes.
