St. Louis, MO (KMOV) - The FBI is just beginning its investigation into threats made against a mosque in south St. Louis.

The mosque has had no problems until threats popped up on the internet just this week.

The American-Islamic Relations (CAIR) Tuesday asked the FBI to investigate the apparent threats that were posted on an anti-Muslim internet site.

The apparent threats come following an arson attack on a Tennessee mosque allegedly by three members of the "Christian Identity" movement and a fire-bomb attack on a Minnesota Muslim business.

The FBI declined to talk to News 4 about this case, but they did say they are taking these threats seriously and are investigating them as a possible hate crime.
