Kaleme.com and Sahamnews.org, the websites respectively of opposition 
leaders Mir Hossein Mousavi and Mehdi Karroubi, reported clashes between 
protesters and security forces erupted near Tehran University and in some parts 
of the capital, including Azadi (Freedom) Square.
It said security forces, deployed in large numbers, fired tear gas at 
protesters who were chanting "Ya Hossein, Mir Hossein!" in support of Mousavi 
as well as "Death to Dictator!" referring to President Mahmoud Ahmadinejad, the 
main target of the protests.
Another opposition website Rahesabz.net reported that police arrested five 
people in Tehran during the demonstration, while 10 protesters were detained in 
Iran`s second largest city of Mashhad.
Sahamnews.org said protesters were gathering in clusters "sporadically near 
Azadi Square but were being extensively attacked by special police forces."

The anti-government protests were called by an opposition group to demand 
release of Mousavi and Karroubi, whose status was unclear on Tuesday as their 
websites claimed the two men had been jailed, while officials denied it.
Kaleme.com said that groups of people were walking on pavements of 
prominent squares and streets in Tehran in an attempt to stage demonstrations, 
especially near Tehran University.
But the online edition of state-run newspaper Iran said that Tehran was 
calm with work going on as usual.
Iran has banned foreign media from on-the-spot coverage of opposition 
protests. (*)
