Rescue workers have found seven more bodies at two Ukrainian coal mines where accidents occurred, raising the death toll to 27.

The accidents in the eastern regions shocked the country and highlighted the dangers of the nation's mining industry. It is believed to be one of the world's most dangerous because of outdated equipment and disregard for safety regulations.

The government said Saturday that Friday's pre-dawn blast at the Suhodilska-Eastern mine in the Luhansk region killed 20 workers, including one body found Saturday. Investigators suspect the accident was caused by an explosion of methane.

In the Donetsk region, rescue workers at the site of an elevator collapse found four more bodies Saturday, raising the death toll there to seven.

Rescue workers at both sites are still searching for 10 missing workers.
