Dozens of people have been injured, including three fire fighters, after a series of explosions at an Oktoberfest celebration in California.
Emergency services rushed to the scene on Saturday night following reports of three consecutive blasts sparking a transformer fire at the Old World Village complex in Huntington Beach.
The complex had been hosting a Bavarian-inspired beer festival.
Multiple people have been burnt, including one person in critical condition who is believed to be a worker at one of the festival's stalls, Huntington Beach Fire Department said.
Three firefighters have also been injured and investigations were ongoing into the early hours of Sunday.
The area was immediately evacuated and a hazardous materials team is currently on scene investigating the explosions.
Ten ambulances also attended the scene but the number of patients taken to hospital remains unknown, according to the fire department.
Witness Kyle Nelson told a local television station that he heard and saw three large explosions in rapid succession coming from the festival, according to the Associated Press.
The Press-Telegram reports that the source of the explosions may have been an electrical transformer but this has yet to be confirmed by authorities.
