Three Ford County men have been charged with arson in the bombing last year of a mosque in suburban Minneapolis.

The U.S. Attorney’s office in Springfield says the men were arrested Tuesday on separate gun charges, and were suspects in the mosque bombing.

But federal authorities in Minnesota charged them with additional counts of arson for their alleged role in the August 5th explosion at the mosque.

Prosecutors say Michael B. Hari, Joe Morris and Michael McWhorter threw a pipe bomb through the window of the Dar Al-Farooq Islamic Center in Bloomington, Minnesota, causing extensive damage, but no injuries.

The three men, plus a fourth who was arrested on the gun charge are from Clarence, town in eastern Ford County.

Authorities in Springfield say Hari, Morris and McWhorter are also suspects in the attempted bombing last November of the Women’s Health Practice, a clinic that performs abortions in Champaign.
