(KLZA)-- Law enforcement agencies across the state of Nebraska were busy Thursday responding to bomb threats.

A Nebraska State Patrol news release says no devices have been found and the threats are believed to be associated with others reported through the nation Thursday.

The Nebraska State Patrol is aware of numerous threats of explosive devices in communities including Falls City, Peru, DeWitt, Fremont, McCook, Lincoln and Omaha.

NSP and the Nebraska Information Analysis Center are working with federal authorities to determine the origin of the threats.
