A miner who was trapped in the flooded Gleision Colliery in Swansea Valley, Wales, has been found dead, police have confirmed.

The unidentified worker was found dead this morning as rescuers attempted to reach the four miners trapped 90m underground.

Rescue operations to save the other three miners are continuing.

Rescue divers entered the flooded mine, owned by MNS, early this morning, but were forced to return above ground.

The debris-filled mine made it difficult for divers to go further than 20-30m.

Seven miners were trapped on Thursday but two managed to escape, while a third is in a critical condition.

Mid and West Wales Fire and Rescue Service's Chris Margetts told reporters in the area that water was being pumped from the mine and oxygen was being pumped in.

The miners are down a 250m main route and were reportedly trapped by water after breaking into old mine workings, reports the BBC.

A device developed by the UK-based company Sure Wave Technology has detected sounds from the mine, confirming that the remaining workers are still alive.
