The fire service had previously said on Twitter that it was responding to an incident after being called to a large explosion in Avonmouth, south west England.
"We can confirm there are multiple casualties on site," a spokeswoman for Avon Fire and Rescue Service said, adding that injuries were serious. "It's very much ongoing," she said.
