WARSAW (Reuters) - The death toll in Poland's second mining disaster in the space of a week rose to six on Monday, Prime Minister Mateusz Morawiecki said, as he promised to investigate safety standards at the pits in question.

A tremor shook Borynia-Zofiowka mine in southern Poland on Saturday morning, just days after methane explosions killed five people in the nearby Pniowek coal mine. Both pits belong to state-owned mining company JSW.
