A "large and extremely dangerous" tornado has hit the city of Washington, Illinois, with pictures showing buildings reduced to rubble and homes torn in half in a city of 15,000 people some 145 miles away from Chicago.
The National Weather Service also confirmed tornadoes touched down near Bone Gap and Miller City, Illinois, in Mount Carmel, Indiana, near the Ohio border, in Vincennes, Indiana, and in Paducah, Kentucky.
A tornado watch for the Chicago metropolitan area was cancelled.

"We have actual whole neighborhoods being demolished by the storm. Fortunately, we are only hearing of minor injuries at this time."
