Nine people have been injured when a van collided with a pickup truck and jumped onto the footpath in Los Angeles, slamming into an outdoor dining area.
Authorities say the incident was a "complete accident."
Eight people were transported to hospitals after the incident on West Pico Boulevard, the Los Angeles Fire Department said on Twitter. A ninth person, an off-duty Los Angeles firefighter, was hurt but did not need to be taken to a hospital, it said.
"Complete accident, nothing intentional," said Lieutenant Jim Lewis of the Los Angeles Police Department.
The incident bore initial similarities to vehicle attacks by Islamist militants in Europe and Israel. Last month, a man drove a van into a crowd of worshippers leaving a London mosque.
Los Angeles' fire department said a 44-year-old man was in critical condition. Three people were seriously injured, and four were in fair condition, with the ages of the seven ranging from 18 to 51, it said.
