Police are investigating the rollover of a tour bus on a snowy New Hampshire highway.

They say the bus was carrying about two dozen Korean citizens from Quebec to Boston on Monday night when the driver lost control on Interstate 93 and the bus rolled on its side into the median, injuring almost everyone aboard.

State police said early Tuesday five passengers were being treated for serious injuries and 18 for lesser injuries. They say the slippery roadway was closed while the bus was removed from where it rolled over in Littleton.

The tour bus accident is the third in the Northeast this month. The crash of a bus headed from an Uncasville, Conn., casino to New York City killed 15 people. A crash on a New Jersey highway killed two.
