All roads directly around the site have been shut off, with the major thoroughfares of Hackney Road and Bethnal Green Road disrupted.

The Metropolitan Police warned that “significant traffic disruption” was expected.

Motorists are advised to use alternative routes to avoid the area where possible.

Bus routes 26, 48 and 55 have been diverted according to Transport for London’s Twitter feed.

Police have advised motorists to avoid the following roads:

Old Bethnal Green Road
Warner Place
Squarres Street
Bethnal Green Road
Cambridge Heath Road
Hackney Road.

The London Fire Brigade tweeted at around 3.30pm: “We’re working with the Police and (Tower Hamlets Council) at unexploded WW2 bomb in #Bethnal Green. 100m hazard zone in place.”

The 500kg bomb was discovered by contractors working in Temple Street.

Around 150 people have been evacuated.

The discovery comes after an incident on March 23 this year when a bomb was discovered in Bermondsey. Residents within 200m of that device were told they weren’t allowed home. Police put a 400m cordon up when the device was discovered at a building site in Grange Walk. It was removed the following day.
