Unseen pictures from World War One have been released showing what was then the world's largest explosion.

Sailor Victor Magnus captured the scene when a ship carrying explosives caught fire in Halifax, Canada, resulting in the deaths of 2,000 people.

The explosion, on Thursday 6 December 1917, almost wiped out the town.

Mr Montague's daughter, Anne Foreman from Cornwall, is to take the pictures to the Imperial War Museum in London.
