LINDSAY HILSUM: They tried to gather in Hafe-e-Tir Square this afternoon, several thousand people braving the heavy presence of militia and riot police, helicopters overhead.
The opposition leader, Mir Hossein Mousavi, said on his Web site that protesting against lies and fraud was the people's right, but he wasn't there himself. A senior judge suggested that Mr. Mousavi should now be arrested.
Pictures were posted online today showing police, dressed in black, and Basij militia, in green fatigues, beating and arresting two men. They seemed to be in a car park or garage. Unknown people filmed from above.
The police pull up the first man's T-shirt over his head to blindfold him and lead him away. Then, they start to tie up the second man. Half a minute later, women scream and a shot is heard. The policemen react by pointing at the second man's head.
We don't know what happened next, but we do know that the Revolutionary Guard issued a statement today saying they would confront "in a revolutionary way" rioters and those who break the law.
A young woman killed on Saturday is emerging as an icon of the protest movement. Neda Soltani is seen here to the left of the man with the gray ponytail, watching the protests. A few minutes later, she is seen dying on the streets, apparently shot by a Basij militiaman.
Iranians at home and abroad are posting online tributes. Security officials reportedly prevented her family from holding a public funeral today. White flowers mark her grave.
Information is trickling out from other cities, these pictures apparently from Tabriz, Mir Hossein Mousavi's home city, on Saturday. There have now been hundreds, possibly thousands of arrests across the country, the authorities saying they picked up 457 people yesterday in Tehran alone.
