 Bomb experts from the British army are now deactivating a bomb in London.

The bomb is near a underground train system and and believed that it is from the world war II.

It was discovered last night and weighs around a ton.  It is located near the river Lea and Bromley-by Bow underground station. 

It started ticking for a while but stopped when the bomb experts poured liquid over it.

The train station has been closed since the bomb was discovered but this is the biggest bomb found in London for decades.
