A charter bus veered off a highway in Northern California and struck a pole early on Tuesday, killing at least five people, authorities and local media reported.
The bus was en route to Sacramento from Southern California at about 3:30 a.m. local time when it suddenly swerved off of California State Route 99 and crashed, CBS Sacramento reported.
At least five of the roughly 30 people aboard the bus were killed, CBS Sacramento said. It was not immediately clear if others were seriously injured.
The cause of the incident in Merced County, about 100 miles south of Sacramento, was under investigation, the California Highway Patrol said in a statement.
The crash forced the closure of a northbound stretch of the highway, the statement said.
