WWII bomb forces huge evacuation in Greece

It is thought to be one of the largest wartime bombs to be found in urban Greece in addition to being one of the largest mass evacuations.

The bomb was discovered during road works last week and is due to be disposed of on Sunday (local time).

Officials say it is too degraded to tell if it is German or an Allied bomb.

Residents within a radius of about 2km of the bomb will have to evacuate the area before Sunday morning, security officials said.
