Swiss prosecutors have opened an investigation into the liberal Islam critic Saida Keller-Messahli over libel allegations against a controversial Islamist preacher.
"We opened an investigation against Ms Keller-Messahli on suspicion of slander and defamation", a spokesperson for Bern's prosecution office told the Swiss News Agency on Monday. If a complaint is made containing allegations of defamation, the Swiss authorities must automatically take action.
The allegations concern the controversial Libyan imam Abu Ramadan, who was caught up in a media storm last year. Ramadan is accused of having preached messages of hate at a mosque in French-speaking Switzerland.
