Military personnel from 621 Squadron, 11 EOD Regiment, Royal Logistics Corps, are expected to work through the night to stabilise and defuse the bomb, which is believed to have been dropped over London during German bombing raids in the early 1940s but did not detonate.
The bomb in question has lain undisturbed deep in the ground for 70 years but was unearthed this afternoon.
An Army spokesperson said:
We can confirm that a specialist military bomb disposal team from 11 EODRegiment, Royal Logistics Corps are on site in Bethnal Green and are assisting the Police with the on-going incident involving a WWII German aircraft bomb that was discovered earlier today.
As with previous incidents, it is important that people follow any advice given by the Police.
The military EOD teams have extensive experience with these situations, having operated in Iraq, Afghanistan and Northern Ireland.
Earlier this year they detonated similar devices discovered in Wembley and Bermondsey.
