Tehran witnesses the return of calm for a second day after security forces prevented new election-related demonstrations in the Iranian capital.

Although protesters had earlier announced that they would gather in Tehran's Ferdowsi square, Press TV correspondent reported no protest had been staged in the area.

This is while some 200 protesters gathered in Tehran's Haft-e Tir square but left after the arrival of security forces on the scene.

Previously-planned Azadi square demonstrations, which were announced illegal by the Interior Ministry, were also cancelled due to heavy security presence.

Following the victory of President Mahmoud Ahmadinejad in Iran's 10th presidential elections, the country has become the scene of rallies with defeated presidential hopefuls Mir-Hossein Mousavi and Mehdi Karroubi rejecting the result as fraudulent and demanding a re-run.

On Saturday, acting Police Chief Brigadier General Ahmad-Reza Radan warned against any illegal gatherings, saying that the police would firmly deal with any illegal rallies and those who plan such activities will be prosecuted.
