WWII-Era Projectiles Found in Massachusetts River by Magnet Fishers

The discoveries, made within a week of each other, have sparked curiosity about the presence of old military ordnance in the Charles River.

Two military projectiles, believed to be from World War II, were discovered in the Charles River in Needham, Massachusetts, within the same week by magnet fishing enthusiasts.
The Massachusetts State Police Bomb Squad safely detonated both projectiles, which were found in a deteriorated state.
The discoveries have raised questions about why these old pieces of ordnance are suddenly being found in the river.
Magnet fishing, a hobby that gained popularity during the pandemic, involves using strong magnets to retrieve objects submerged in water.
Local magnet fishermen speculate that the projectiles may have fallen off shipments in the river during World War II.
