Hari, McWhorter, and Morris face federal charges in for the bombing at the Dar Al-Farooq Islamic Center as people were getting ready for prayer.
The three men, plus a fourth who was arrested on the gun charge, are from Clarence, a small unincorporated town in eastern Ford County.
The men - identified as Michael B. Hari, 47; Joe Morris, 22; and Michael McWhorter, 29 - also face charges of possession of a machine gun and are suspects in the attempted bombing of an IL abortion clinic this past November, according to the US attorney's office in Springfield, Ill.

Hari allegedly told McWhorter's brother when he dropped off the guns, "The police will want to come talk to me; can I keep them here until I speak to them?" said the affidavit.
During a press conference Tuesday, Jaylani Hussein, executive director of the Council on American-Islamic Relations, thanked law enforcement for their swift action in arresting the three suspects.
