Five people were killed Saturday in a crash involving seven motorcycles and at least one other vehicle on a rural desert highway east of San Diego, authorities said.
The five fatalities occurred in the collision shortly before 1 p.m. on Route 98 near Ocotillo in Imperial County, just miles from the U.S.-Mexico border, California Highway Patrol spokesman Pablo Torrez told the Imperial Valley Press.
Torrez said he did not know whether one or two vehicles other than the motorcycles were involved.
It was not clear which vehicles the dead came from or why so many motorcycles were riding together.
The CHP had earlier reported six injuries, but it was not clear if any of those six were among the dead.
The Highway Patrol's Multiple Accident Investigation team from San Diego was called in because of the accident's size, Torrez said, and two emergency helicopters were dispatched to the site to airlift the injured.
The Border Patrol closed the highway for much of the day.
Dispatchers with the CHP would not release any information on the collision when reached by the Associated Press, and they said there were no officials available to talk.
Ocotillo is about 80 miles east of San Diego.
