LINCOLN, Neb. (AP) — Several sections of Interstate 80 are closed in eastern Nebraska because of accidents in the snowy conditions Sunday morning.

Officials are encouraging people to stay off the roads in eastern Nebraska and Iowa if at all possible Sunday.

Lancaster County officials closed Interstate 80 in the county Sunday after a semitrailer truck accident that caused serious injuries.

Near Aurora, westbound Interstate-80 was closed Sunday morning and traffic was being routed around the area at the Aurora exit.

Further west, a semi became jack-knifed across both eastbound lanes near Shelton. Hall County officials are detouring traffic around nine miles of the interstate.

National Weather Service meteorologist Brad Fillbach told the Des Moines Register that “Driving is not going to be the smartest thing to do today. Stay home if you can.”

LINCOLN, Neb. (AP) — Lincoln police suspect the 17-year-old student arrested in connection to two fires at a high school likely started them out of boredom.

The Lincoln Journal Star reports (https://bit.ly/1Ht8Cau ) the student was arrested Friday on two counts of arson for the fires, the second of which prompted officials to close the school Thursday.

Students and staff were evacuated twice due to the fires. The first time was after someone started a fire in a trash can, and the second was after someone set fire to wrestling mats stored in a hallway near a gymnasium.

Officer Katie Flood says police believe the teen started the fires because he was bored. She says authorities think he used a lighter to start them.

The student has not yet been formally charged.

LINCOLN, Neb. (AP) — Investigators are working to determine what caused a fire that heavily damaged a Lincoln bar and knocked out power in the surrounding area.

The fire started at the Karma Nightclub and Cabaret around 7:15 p.m. Saturday. Everyone was evacuated safely, but it took several hours to control the fire.

The club’s owner Kyle Baun says he was heartbroken when he arrived to see his business in flames.

The roof collapsed during the fire. Lincoln Fire Battalion Chief Leo Benes said the business is a total loss.

Karma had been open just over a year. Previously the club was called The Q.

Bryan Ruhs, who worked as a DJ, says it was hard to watch the fire because the club was the first gay bar he ever went to.

OMAHA, Neb. (AP) — The winter storm has forced airlines to cancel some flights in Nebraska and Iowa, but the airports are operating normally despite the snow.

The main problem area Sunday for airports in Omaha, Lincoln and Des Moines was flights headed to and from Chicago. Most of the cancellations involved one of Chicago’s two major airports.

Eppley Airfield spokesman Tim Schmitt says about 20 flights to and from Omaha were cancelled because of the storm. But the airport had two runways clear and planes were landing without problems.

Lincoln airport officials said there had only been a couple cancellations Sunday.

Des Moines International Airport spokesman Andrew Wall says a few flights were cancelled Sunday, but those were mostly the ones that go back and forth to Chicago all day.

OMAHA, Neb. (AP) — A new program will allow some of the top security specialists working for U.S. Strategic Command to study leadership at the University of Nebraska at Omaha this semester.

The group of 10 that begins their 13 weeks of study at UNO this weekend includes some of the top civilian security specialists.

The students in the program were chosen by leaders at Strategic Command, which is based at Offutt Air Force Base.

In addition to graduate-level leadership coursework, the students will have the chance to learn from business leaders from Union Pacific and First National Bank.

FREMONT, Neb. (AP) — Several children attending a Washington County child care are under a 21-day quarantine after health officials announced that a child with a confirmed case of the measles could have exposed others at the facility to the disease.

Terra Uhing, executive director of Three Rivers Health Department, said her department has been working with Little Blossom’s Childcare to identify possible exposures.

Uhing said any child not vaccinated is being held out for 21 days.

Uhing says the Blair child care facility was caring for several children younger than a year old — too young to have been vaccinated for measles.
