Another story with Muslime construction workers:
Before a few monthes I have heard about thousands of snakes that attacked an area in Pakistan. Construction workers wanted to re-activate an old well from of few hundreds years ago. In the moment they removed the seal from it thousands of snakes attacked them and they fled. After that the snakes attacked the villages near the location. In the end a lot of Pakistinians killed the snakes with spades and paddels.
Perhaps somebody can find the source on the web.
