Despite the warning issued by the Revolutionary Guard, thousands of protesters take to the streets of Tehran.
Iranian riot police have fired tear gas to break up a new opposition rally in the centre of the capital Tehran, hours after a stern warning to protesters.
Some 1,000 protesters had gathered on Haft-e Tir Square despite a warning from Iran’s Revolutionary Guards against holding unapproved rallies.
An unconfirmed report says riot police fired bullets into the air.
The Guards, an elite armed force, vowed to crack down on new street protests over the presidential election results.
On Friday Ayatollah Ali Khamenei banned protests, prompting street violence in which at least 10 people died.
Internet postings on Twitter, Facebook, and an Iranian opposition leader’s Web site mentioned a 4 p.m. (7:30 a.m. ET) vigil for Neda — the young female protester who became a rallying cry and a symbol for the opposition after her death was caught on camera.
It is unclear, however, if the people were at the square for a vigil. Signs and banners about Neda and candles have not been seen.
