Quake confusion as bomb explodes in Vienna

Austrian authorities say what initially appeared to be a small earthquake which rattled Vienna turned out to be the explosion of a large Second World War bomb.

Investigators think the bomb weighed up to 500kg. It lay buried for decades in the garden of a home in the Austrian capital, and no one knew it was there.

When it exploded, officials thought the tremor was caused by a minor earthquake which had somehow set off the bomb.

But experts at the scene today said there was no quake. The bomb left a crater when it exploded Friday evening, but no one was injured.

Unexploded ordnance from the war remains in many locations across Austria.
