More than two dozen rescue workers are trying to free two cavers who were trapped on Saturday, August 17th, by rising water in the Wielka Sniezna cave complex, in the Tatra mountains, in southern Poland, Polish media said on Sunday August 18th, AP reported.
Rescue officials have not yet managed to make contact with the two cavers, the broadcaster, TVN said.
Explosives would be used to widen passages in the cave, in an attempt to reach the trapped cavers, the head of the local rescue team, Jan Krzysztof said, reported by TVN.
The operation could take days or even weeks, he added. Experts from neighbouring Slovakia are coming to help the rescue operation.
Wielka Sniezna is the deepest and longest cave in Poland, consisting of a complex system of passages, wells, and running water.
