Three people are dead and a regional airport has been heavily damaged after powerful winds including a tornado swept across the upper U.S. Midwest.

At least three people were killed in a small North Dakota town as tornadoes ripped through the state. All three victims lived in Enderlin, a town of 800 residents about 40 miles southwest of Fargo, according to the Cass County sheriff’s office. They have been publicly identified only as two men and a woman.
