British Army dismantling 'enormous' WWII bomb in London

LONDON, England (CNN) - A British Army bomb disposal team is working carefully to dismantle a large unexploded World War Two bomb unearthed this week near the future Olympic Park in London, officials said Friday.

Contractors clearing a site in east London unearthed the 2,200-pound German bomb Monday, the Ministry of Defense said, and called in the army experts to make it safe. The bomb measures four feet by two feet and is the largest one found in the capital since 1975, defense officials said.

"It's enormous," said Simon Saunders, the spokesman for the British Army's London district.

The bomb's discovery has forced subway and train lines in the area to shut, transportation officials said.
