``It's just a coincidence. A natural gas explosion leveled a house Thursday, and explosions six blocks away on Saturday leveled a second house and knocked a neighboring one off its foundation, in a town 60 miles northwest of Chicago. The sites were fed by two separate gas lines and Northern Illinois Gas calls the explosions coincidences. In both cases, officials said they had no idea what caused them. The blasts' causes may not be known for weeks. No serious injuries resulted. In Thursday's explosion, a man's mattress carried him to safety when it was sent flying into the driveway.
