An assailant opened fire at a light rail yard in San Jose, California, on Wednesday morning, killing an unspecified number of people and injuring others, the county sheriff's office said.
Santa Clara County Sheriff's Deputy Russell Davis told reporters that "there are multiple injuries and multiple fatalities" and the assailant was dead.
"I can't confirm the exact number of injuries and fatalities," he said. He said he could not identify the shooter or confirm how they died.
