BEIRUT - A Syrian rights activist says security forces have fired on protesters during a funeral in a volatile southern city where at least 25 were killed a day earlier.

Ammar Qurabi heads Syria's National Organization for Human Rights. He said the group's information is coming from residents and eyewitnesses in the city of Daraa.

Qurabi told The Associated Press that several people were wounded in Saturday's shooting as burials were taking place.

Friday marked the single bloodiest day of the uprising, with at least 37 people killed nationwide.
