More Casualties From the Great War

A shell or grenade buried in western Belgium since World War One, has exploded, killing two people.
At least two more were injured, one of whom is in critical condition.
The device was set off as workmen at a building site in Ypres were trying to dig it up.

The British and the Germans fought for years around Ypres. Shell-fuzing was a bit of a new art back then, I've seen estimates that the percentage of dud rounds was over 30%. That's if it was a shell. For all we know, it could have been a Mills bomb that was dropped by a soldier. Nearly a century of corrosion and it might have looked like just another stone.
