A tour bus careened through a guardrail along an icy Oregon highway and several hundred feet (meters) down a steep embankment Sunday, killing nine people and injuring more than 20 others, authorities said. The charter bus carrying about 40 people lost control around 10:30 a.m. on the snow- and ice-covered lanes of Interstate 84, according to the Oregon State Police. The bus came to rest at the bottom of a snowy slope. More than a dozen rescue workers descended the hill and used ropes to help retrieve people from the wreckage in freezing weather. The bus driver was among the survivors, but had not yet spoken to police because of the severity of the injuries the driver had suffered. Lt. Greg Hastings said the bus crashed along the west end of the Blue Mountains, and west of an area called Deadman Pass, according to a report of the Associated Press.
