A large-scale evacuation has begun in central Berlin so that experts can defuse a World War Two bomb.

The evacuation affects about 10,000 people and the zone includes homes, government ministries and museums.

The operation is causing severe transport disruption, with trains unable to stop at the city's main railway station.

The 500kg bomb, thought to be made in Britain, was found during construction work in Heidestrasse.

Buildings are being cleared in an 800m radius around the site.

Berlin's famous Charité university hospital and a military hospital have been partly shut down.

Berlin police tweeted a photo of their bomb disposal team at the scene, poised to defuse "the source of all the evil".

Thousands of unexploded bombs from the 1939-45 war are found every year. The Berlin bomb was found last Wednesday.
