Divers Uncover Undetonated WWII Bomb From the Bottom of Australia's Sydney Harbor

It's been more than 70 years since World War II ended, and undetonated explosives from the conflict are still being uncovered around the globe. The latest WWII-era bomb was found in Australia's Sydney Harbor by a pair of recreational divers, the Newcastle Herald reports.

Dive instructor Tony Strazzari and his friend Paul Szerenga have made a hobby out of donning their diving gear and searching the harbor for old glassware and bottles. When they continued this ritual on February 21, they came across something out of the ordinary: a 15-inch bomb.

Strazzari worried that a ship's anchor might activate the device, so after retrieving it from the silty harbor floor he hauled it up to the surface. The two divers contacted the New South Wales police and "baby-sat" the bomb while waiting for someone to show up. According to a spokeswoman from the police department, the rusty bomb was unable to detonate, but it was seized by military personnel as a precaution.

New South Wales was a target of Japanese submarines during the Second World War. While this newly discovered artifact left over from the war was taken care of without too much trouble, that isn't always the case. Earlier this month, an unexploded bomb found in the River Thames led to an entire airport being shut down.
