Police use tear gas on protesters
Greek riot police have used tear gas and pepper spray to disperse Muslim protesters during a rally against a film produced in the United States that denigrates Islam's Prophet Mohammed.
No injuries were reported.
Police said six people were detained during the demonstration in central Athens. About 600 people attended the rally, which featured heated speeches but was mostly peaceful.
It briefly turned violent when some in the crowd clashed with riot police, throwing objects at them. Three cars were damaged and three shop windows smashed.
Police had cordoned off Omonia Square and prevented the protesters from marching to the US Embassy, about two miles away.
Banners in English denounced the film, called on the US to hang the filmmaker and told President Barack Obama "we are all with Osama".
