Two miners were killed and one remained trapped underground after an overnight tremor caused a partial collapse in the Myslowice-Wesola mine in southern Poland. The tremor occurred 870 metres underground, and 15 miners were in the danger zone. Twelve were rescued and taken to the hospital due to injuries. Rescuers are still trying to contact the remaining miner trapped underground. This incident marks the fourth accident resulting in fatalities at a coal mine in Poland this year.
