Unknown event in Oregon, Newport area, United States of America on Mon 10th October 2022

Three explosive hand grenades washed up on a beach in Oregon last week, leading local police to warn residents. The grenades, found on the beach in the Newport area, between Yaquina Bay State Park and Agate Beach, were labeled as "M116A simulator hand grenades," and each was white and cylindrical. The devices were marked “Warning: Explosive" in large red letters, according to an image shared by the Newport Police Department on Wednesday. “If you encounter such a device, please do not handle or attempt to move it,” the department said in a statement. “Call the police to report the device’s location.” The Oregon State Police Bomb Squad responded to the calls and seized the devices that were found, the department said. Simulator grenades are used in training exercises and cause loud noises when detonated. The purpose of the grenades is to train soldiers with realistic battlefield sounds and effects, according to a company that supplies the grenades to the Army. Such devices simulate an explosion 6-12 seconds after the grenades are activated. An unexploded Navy mine was discovered on the shore in Broward County, Florida, last year. In a similar manner, the device was labeled "inert," which meant it could be used for training exercises. However, the word does not rule out the possibility that the device was active, and a bomb squad and the Air Force were called to the scene, according to Local-10. Real Navy sea mines are used to damage enemy submarines and surface ships. Authorities with the Air Force took the dummy mine away for further investigation.
