A charter-style bus near San Diego toppled over a highway embankment on Saturday, killing three people and injuring at least 18, NBC News reported.
The accident occurred around 10:35 a.m. local time on Interstate 15 near Fallbrook, Calif., about 60 miles north of San Diego, according to the network.
"We do have what appears to be a charter tour bus that's rolled several times over the side approximately 30 feet," an emergency responder said upon arriving at the scene.
The local fire department tweeted, “We are brokenhearted to report we have 3 deceased on scene."
Charter buses in the area are reportedly often used to transport people to one of the numerous Native American casinos in the greater San Diego area.
The accident happened less than five miles from Pala Casino Spa and Resort in Pala, Calif.
