The death toll from accidents in recent days at two coal mines in southern Poland has increased to nine after four miners were brought to the surface and pronounced dead, authorities said on Sunday.

The miners were among 10 missing since an underground tremor and methane gas discharge at the Borynia-Zofiowka mine early on Saturday.
