WARSAW (Reuters) -Rescue teams are trying to bring 27 coalminers trapped under ground to the surface after their pit in southern Poland was struck by an earth tremor, a company spokesperson said.

PGG spokesperson Aleksandra Wysocka-Siembiga said the tremor occurred at around 0600 GMT about 1,200 metres (3,960 feet) below ground at the Rydultowy mine.

She said 68 miners had been in the area at the time, 41 of whom had already been brought to the surface. Fifteen miners have been transferred to nearby hospitals but are all in good condition, she told broadcaster TVN24.

"The remaining miners are being brought out. We still don't have contact with two miners", she said.

Television footage showed helicopters and ambulances at the mine. Wysocka-Siembiga earlier said more than 10 rescue teams were on site.
