Castine, Maine Unexploded cannonballs from the War of 1812 were safely removed from the Castine Historical Society in Maine. Kate McMahon, the society's executive director, said that she believes someone donated the cannonballs decades ago and that the UXO sat in storage until recent concerns arose about their explosive threat.

According to McMahon, the news that Fort McHenry in Baltimore was evacuated recently after unexploded cannonballs were found during utility work, prompted museum staff to examine the cannonballs. The examination revealed that three were likely black powder cannonballs.

The Maine State Police bomb squad responded to remove the three large cannonballs, along with 16 smaller cannonballs which appeared inert. McMahon said that the smaller munitions were "unlikely to contain explosive powder," but the museum "wanted to ensure both the safety of our collections and facility, as well as the general public."

The bomb squad wasn't done there, they also removed two dozen cannonballs from the Wilson Museum in Castine on that same day. All the ordnance was slated for controlled detonation.

In a press release Isleta Pueblo Tribal Council Governor Eugene Jiron said, "We truly appreciate the Air Force coming out here. Seeing everyone working together shows we have a strong partnership with Kirtland. This cleanup matters to our community, we have families who graze cattle here and we allow hunting in these areas. Clearing old munitions helps keep them safe."

The Pueblo and Kirtland AFB have committed to work together to address buried ordnance in other areas in future joint efforts.

Orlando, Florida The Orlando Fire Department and its Arson Bomb Team responded to a potential explosive device on Friday afternoon.

Harpswell, Maine The bomb squad and EOD were called in after an unexploded WWII-era artillery shell was found at a home in Harpswell. According to the Cumberland County Sheriff's Office, the munition was discovered during an open house.

The Maine State Police Bomb Squad and Maine Air National Guard's 101st EOD team, responded to identify the device as a British artillery round. It was transported to a safe area where a controlled counter charge revealed it was inert.

Maine State Police reminded citizens who come across any suspicious device to never touch, move, or attempt to examine the item. Instead, immediately contact local law enforcement.

Hong Kong Officers from the explosive ordnance disposal bureau responded swiftly after construction workers discovered a suspected wartime bomb found at a construction site at Hong Kong International Airport. Police evacuated approximately 900 people from the area while EOD disposed of the British wartime mortar by controlled detonation.

EOD were able to complete operations just four hours after the initial report of the find. No injuries were reported and airport authorities said flight movements continued as normal and were not affected by the incident.

Fort Pierce, Florida A live grenade was discovered among donated items at a Goodwill store in Fort Pierce, leading to a prompt evacuation and response from the bomb squad. The Fort Pierce Police Department was called to the Sabal Palm Plaza store after a suspicious object was reported.

The St. Lucie County Sheriff's Office Bomb Disposal Unit safely removed the device without incident, and authorities quickly determined there was no ongoing threat to public safety. The source of the grenade is currently under investigation, though officers do not believe there was any malicious intent.

The Goodwill organization and law enforcement officials in certain regions have described these incidents as "oddly common" or happening "about every 9 months or so at one of our stores," often involving World War II-era memorabilia.
