Two people have suffered injuries after an "explosion" rocked the UK's largest steelworks causing a fire to break out.
Locals reported their houses shook with the force of a blast at the Tata Steel site in Port Talbot in the early hours of this morning.
Several bright flashes could be seen in video purported to be of the incident shared online.
