Earthquake sets off buried WWII bomb

Austrian authorities say a small earthquake set off a large World War II-era bomb in the garden of a Vienna home.
No one was injured in the explosion.

Investigators think the bomb weighed up to half a ton. It lay buried for decades in the garden, and no one knew it was there.

But when a minor quake shook parts of the Austrian capital, the bomb exploded.

Officials say the homeowner heard a dull bang Friday evening and went outside to see what happened.

Experts were still on the scene Saturday to examine the crater left by the blast.
