According to Reuters, ever since mid-January, various electronic devices have been spontaneously combusting in the now evacuated town of Canneto di Caronia, Sicily; at this point, the fires are almost daily. The town has been disconnected from the larger electrical grid and was hooked to a generator, but that, too, caught fire. Even unplugged items have succumbed. Nothing seems to have burst into flame except where there is someone present to witness it, but the police no longer suspect a prankster — after witnessing wires catch fire without cause. Scientists have yet to explain the phenomenon (although unproven theories abound), leading many people to look to supernatural causes.
