The partial collapse of an abandoned house in a northern village has revealed a cache of hand grenades and ammunition believed to have been hidden there for many decades, state ERT television reported Tuesday.

Army explosives experts safely defused the weapons and removed them from the ruins of the house in Kalohori, near the town of Kastoria, to be destroyed.

The badly corroded nine grenades and 130 rounds of ammunition appear to date to World War II, although they could also have been hidden in the old house during the 1946-1949 Civil War.

They were discovered by an elderly woman who had gone to check up on the building – which belonged to a deceased relative of hers – after heavy rains in the area. She found the upper storey had collapsed, together with the roof, leaving the weaponry in plain view.
