A prayer service has been held to remember the victims of two explosions which destroyed a wood mill in Bosley in Cheshire a week ago.
Four people were left unaccounted for following the blast. Fire and rescue teams have found three bodies so far.
The owners of Bosley mill have released a statement speaking of their "devastation" at the loss of at least three colleagues.
It comes nearly a week after the tragedy happened during which time the families affected say they have had no contact from Wood Treatment Limited.
The statement said they had now contacted all four families involved and are "discussing how best" to help them.
It added: "They were all highly valued members of staff and our thoughts and deepest sympathies are with their families at this difficult time.
"The mill has been part of village life in Bosley for almost 90 years and we share the pain of the community.
"Our primary focus remains supporting the families of those affected, our employees and the local community as best we can while our site and facilities remain closed.
"We are absolutely committed to establishing the cause of this incident and will continue to co-operate fully with the emergency services and Health and Safety Executive. Company staff have been on site since last Friday assisting the authorities.
"We take the safety of our employees extremely seriously but it would be inappropriate to speculate about the circumstances of this incident until the full investigation is complete."
An emotional prayer service has been held to remember the victims of the Bosley mill explosion, a week on from the disaster.
Kelvin Barks told ITV News his brother William, who was an engineer at the factory, tried to get a new job but 'had bills to pay'.
Dorothy Bailey, Derek Moore, Jason Shingler and William Barks have been missing since Friday's explosions.
