TEHRAN Tens of thousands of supporters of defeated presidential candidate Mirhossein Mousavi gathered in downtown Tehran on Wednesday for a fifth day of protests against last week's election result, witnesses said.
Mainly dressed in black and also wearing wristbands and headbands in Mousavi's green campaign colors, they assembled in Haft-e Tir square and streets around it, the witnesses said. Most of the protesters were silent and making victory signs.
One street leading to the square was packed for several kilometers, witnesses said.
At least one young woman held a picture of one of those killed during post-election violence that has rocked Iran since official results of the election were announced on Saturday, showing Ahmadinejad had won by a landslide against Mousavi.
Mousavi and his backers say the election was rigged. The authorities deny it. Fars News Agency earlier quoted Interior Minister Sadeq Mahsouli as saying "no permission has been issued for a gathering or rally in Haft-e Tir Square" on Wednesday.
One witness said police were blocking traffic on one road leading to the square.
As in previous pro-Mousavi rallies, demonstrators held pictures of him as well as green balloons, witnesses said.
