A WWII hand grenade appeared in a grocery, in a town near Rota, southern Spain in a bag of potatoes imported from France. The greengrocer noticed that the UXO, covered with sand, was kind of heavy and metallic for a potato. After reporting to the authorities, a Navy EOD team took care of the object. It seems something like that happened in Naples, Italy weeks ago, and in Oviedo, northern Spain, some time ago. Both times, those seem to be Mk2 Fragmentation grenades, the model used by the US armed forces in WW2

In France, the UXOs from both World Wars are still a severe trouble wich takes an undisclosed (kind of censored) number of farmer´s lives every year. Imagine yourself mowing your lands and awakening one of these.
