A Rwandan judge Monday turned down a bail application by an American lawyer charged with denying Rwanda's 1994 genocide and publishing articles that threaten the country's security.

Peter Erlinder pleaded not guilty to the charges in court last Friday and asked to be granted bail so he could return home for medical treatment.

The U.S. lawyer is accused of violating Rwanda's laws against minimizing the genocide in which hundreds of thousands of Rwandans, the vast majority of them ethnic Tutsis, were massacred by extremist Hutus in 100 days. Erlinder doesn't deny massive violence happened but contends it's inaccurate to blame just one side.

"The medical report which Erlinder presented to court only shows that he was hospitalized twice but it does not convince court that his hospitalization was a result of detention," said Judge Maurice Mbishibishi

He said Erlinder will remain in detention for 30 days and can appeal the bail decision in five days time. His lawyers said they are going to appeal it immediately in Rwanda's High Court.
