Pictures taken at the site of the bomb in Great Yarmouth have revealed the impact of its sudden explosion.

The sand wall erected to encase the Second World War bomb has been partially blown away after the device went off on Friday afternoon.

An estimated 400 tonnes of sand had been brought in to shield the bomb and prevent it from damaging nearby properties.

The explosion caused part of the sand wall to collapse, with some windows in a building close to the site found smashed.

All army and emergency service personnel was accounted for after the blast and there were no reported injuries.

It came after an announcement was made that the final phase of the delicate operation to disarm the bomb by specialist teams was under way.

The bomb was initially found during dredging work to construct the third crossing in Southtown Road at about 11.30am on Tuesday.
