Iranian students defy security clampdown and protest
Iranian students have defied a security clamp down to stage anti-government protests throughout the country, witnesses and opposition groups say.
Unconfirmed reports say about a dozen people have been arrested, including some at Tehran University in the capital.
Last year's protests led to clashes with security forces as students lashed out over the disputed re-election of President Mahmoud Ahmadinejad.
This year's protests appear smaller, and there are no reports of violence.
Pro-government rallies have also been held across the country.
