BREAKING: At least one person has died in massive explosion at UK power station (VIDEO)

An explosion has killed at least one person and injured five others today at Didcot Power Station in Oxfordshire. Three people are still missing. The event has been called a “major incident“.

At around 4pm on 23 February, eyewitness Adrian Redhead said:

There was this massive explosion … within 30 seconds emergency vehicles were all over the place. The amount of smoke and dust coming across was incredible.

According to the Independent, emergency services have confirmed there have been “a number of casualties”, among fears there were people inside the building at the time of the incident.

Deputy leader of Oxfordshire County Council, Rodney Rose, said:

there has been one fatality, but the rest is currently unknown … we are still trying to find out if this was a demolition … At the moment this is being treated as a collapsed building, not an explosion.

But residents nearby said the explosion sounded like “thunder”.

Images and videos of the event soon appeared on Twitter:

A spokeswoman for RWE NPower – the company that manages the site – claimed not to have been aware of a planned demolition, even though the power station had previously been marked for demolition. In other words, this seems to have been an unexpected event – the causes of which are currently unclear.

Thames Valley Police have said they will be releasing further details as they come to light.
