“On Friday, work began to disarm the explosives remaining in the device, but somehow it detonated, causing a large explosion that was captured on video by a police drone.”
A dredging contractor pulled a 250 kilogram bomb out of the River Yare in Great Yarmouth on February 7. Three days of evacuations later, it went off during disarming. A sandbox wall kept anyone from getting hurt, and a river flood wall took the damage. A World War II bomb still gets to pick its own moment.
