A loud blast has been reported at an Iranian military facility and officials in the country say it was the result of an "unsuccessful" drone attack.
"One of (the drones) was hit by the ... air defense and the other two were caught in defense traps and blew up. Fortunately, this unsuccessful attack did not cause any loss of life and caused minor damage to the workshop's roof," the ministry said in a statement carried by the state news agency IRNA.
