Bomb threats have forced 24 courthouses in Tennessee to evacuate today, the Associated Press reported. A spokeswoman for the Tennessee Department of Safety and Homeland Security said no arrests have been made. The threats were made by telephone to court clerk offices. 

"It's been going on all morning," the spokesman told the AP.
