Prime Minister David Cameron has expressed his sympathy to the miners' families.
The Prime Minister has given his reaction following the death of four miners in a flooded Swansea Valley colliery in South Wales.
David Cameron said:
It is obviously a desperately sad situation, and one can only imagine the anguish that those families are going through and will go through, and clearly the sorrow of losing loved ones.
The men became trapped in the flooded Gleision Colliery near Pontardawe on Thursday morning. The bodies of Charles Breslin, 62, David Powell, 50, Garry Jenkins, 39, and Phillip Hill, 45, were discovered on Friday.
