Dozens of rescuers try to save two trapped cavers in Poland
Explosives could be used to open up route to pair trapped in cavern in Tatra mountains
More than two dozen rescue workers are battling to save two cavers trapped in a cavern in the Tatra mountains in Poland after a narrow tunnel flooded with water.
A representative of the rescue service said on Sunday it had not yet been possible to establish contact with the two cavers and that concern was growing because of their long exposure to extreme conditions.
