An unexploded ordnance from World War II was detonated Tuesday morning after a U.S. Border Patrol agent discovered it near the Arizona-Mexico border July 20.

The agent was patrolling in Bisbee when a MK2 37mm round was reportedly found near the international boundary fence, a press release said.

Cochise County Sheriff's deputies were dispatched to set up a safety perimeter.

On Tuesday, an airman from the disposal unit at Davis-Monthan Air Force Base determined it was a live round. The ordnance was detonated at the location as officials deemed it to be the safest location.
