Hundreds of people took part in rival protests over plans for a mosque near the site of the 9/11 terror attacks, reports BBC News.
Police kept the banner-waving groups apart, although there were no reports of violence between supporters and opponents of the scheme in New York.
Opponents chanted “No mosque, no way” as supporters responded with “Say no to racist fear.”
Developers plan to convert an old building into a 13-story Islamic community center and mosque.
Feelings ran high during Sunday’s protests in Manhattan, close to Ground Zero.
