FAIRDALE, Illinois, Jumada II 21, 1436, Apr 10, 2015, SPA -- Crews searched for missing residents Friday after at least one tornado brought chaos to a tiny northern Illinois town, killing two people, injuring roughly a dozen more and sweeping homes off their foundations. According to AP, the large storm that rumbled across much of the U.S. also forced the cancellation of more than 850 flights at Chicago's O'Hare International Airport on Thursday and dozens of others at the city's Midway International Airport. The outlook was much improved Friday, although about 90 flights were cancelled and dozens of delays were expected. At least two tornadoes swept through Illinois late Thursday. At least one of them struck Fairdale, a community of roughly 150 people about 80 miles (130 kilometers) northwest of Chicago. Two women were killed and about a dozen other people were taken to hospitals with injuries that were not life-threatening. --SPA 21:47 LOCAL TIME 18:47 GMT www.spa.gov.sa/w
