There is a "huge risk" that the remaining section of Didcot Power Station could collapse, with emergency crews prepared for it to happen "at any minute", officials have said.
Oxfordshire Fire Service chief fire officer Dave Etheridge said the main priority was to reunite families with their missing loved ones, warning it was "highly unlikely" the three workers still unaccounted for had survived.
He said they were working closely with building and structural engineers and construction experts to help keep search and rescue officers safe as they continue to work through the rubble.
Clearly, the fact that we're dealing with here is that we had a complete building that was being prepared for demolition. Part of that building has collapsed.
The other half has been subject to the same approach, so consequently we are working on the principle that that second building could collapse at any time.
One person - a member of the demolition team - has already been confirmed dead, while five others remain in hospital in what police say is a "serious but not critical" condition.
Frustrated families of those missing since the power station collapse two weeks ago say they are heartbroken that rescue work has halted.
