The graves of hundreds of miners killed in one of the UK's worst pit tragedies could be desecrated if controversial drilling plans go ahead, campaigners say.
Up to 255 victims of the 1934 Gresford Colliery disaster lie underground in a mass tomb close to where Dart Energy want to drill for coal bed gas.
But the move has outraged relatives of the dead in Wrexham, North Wales, who have branded the idea "disgusting".
And angry neighbours say any drilling or fracking ? using high-pressure water jets to extract fuel from rock ? near to the burial site would be an insult.
GP Energy, a subsidiary of Dart, was refused permission to drill by Wrexham Council, but the Welsh Assembly overturned that ruling.

The company could start work at any time, but face protests from campaigners who were this week on the verge of eviction by bailiffs from their camp on the farmland site.
Dart Energy insist their drilling will take place one kilometre away from the bodies, but many locals want a five-mile exclusion zone around the site.
Steve Bellis, 52, whose granddad worked in a neighbouring mine, said: "The gas will be extracted from the lungs of dead miners for profit.
"This cannot be allowed to happen. The Welsh Government have overturned the wishes of the local people and have shown no regard for the memory of the miners.
"What has the world come to when respect and dignity cannot be afforded to the miners and families of the miners who lost their lives?"
The 80th anniversary of the Gresford pit disaster ? which claimed the lives of 266 miners ? was marked two months ago.
Only 11 bodies were ever recovered ? the others lie deep below the surface, along with the wrecked pit site.

The colliery reopened in January 1936 and finally closed in November 1973.
Ruby McBurney, 83, was only three when her dad William Crump, 36, perished in the disaster.
The retired nurse and mum-of-five said: "It would be very insensitive to run a business close to all these graves.
"We want a five-mile exclusion zone for any work close to the graves.
"The disaster was devastating for the community. It would be very wrong to put all this machinery on such a poignant spot."

Retired reverend David Griffiths, 76, lost two great-uncles in the tragedy.
He said: "I worked down that pit. There would be a lot of upset if any fracking or drilling went ahead."
If underground gas suitable for extraction is found after test drilling, there could be further planning applications to get the gas out.
A Welsh Government spokeswoman said: "Whilst oil and gas licensing is a matter for the UK government, there is a strong regulatory framework in place which requires a developer to obtain all the necessary consents and licences before any hydraulic fracturing can take place."
A spokesman for Dart Energy, which is based in Stirling, Scotland, said: "Our drilling will be one kilometre from the Gresford mine workings.
"The idea that we will be drilling into where bodies are buried is incorrect."
