A tornado struck an oil workers man camp Monday night in western North Dakota, injuring nine and destroying eight trailers.

Eight of the injured were treated and released from McKenzie County Memorial Hospital, according to Jerry Samuelson, the county’s emergency management director.

The ninth victim was airlifted to a hospital in Minot, Samuelson said.

No details about the extent of that person’s injuries or identity were immediately available.

The tornado touched down around 7:50 p.m. local time at the camp about 5 miles south of Watford City, the National Weather Service reported.

Watford City is in the west of North Dakota, about 30 miles southeast of Williston, the city at the heart of the Bakken oil boom.

The National Weather Service said the twister touched down by U.S. Highway 85.

Two other tornadoes were reported, along with baseball-size hail, Samuelson said.

“Obviously, we’re very fortunate there are no deaths, to our knowledge,” he told NBC News.

The American Red Cross said it was setting up a shelter in the civic center in Watford City with 40 beds.

Tornado warnings had been issued earlier Monday evening for Dunn and McKenzie counties.
