Investigators spent Monday combing through smoldering debris after a fire started at the Islamic Society of Joplin at about 3:30 a.m. earlier that day.
It was the second fire to hit the mosque in little more than a month. A fire reported around the same time on July 4 has been determined to be arson, but no charges have been filed.
Investigators from the FBI, the Bureau of Alcohol Tobacco and Firearms, and the Jasper County Sheriff's Department responded to the site, located in a former church on the outskirts of Joplin. Fortunately, no injuries were reported.
FBI investigators said any act of violence against a house of worship is taken very seriously.
About 50 families belong to the Islamic Society of Joplin, which opened in 2007 as a mosque and community center.
