Accidents in three mines in China have killed at least 30 people and left 13 miners trapped.
The official Xinhua news agency says all 28 workers in a mine in northwestern Shaanxi province died when an underground cable caught fire on Saturday night.
The report also said rescuers had retrieved the remains of five of the miners early Sunday.
In a separate incident, Xinhua says an explosion in a coal mining area in Hunan province killed two people on Sunday.
Thirteen workers were reported trapped underground after a coal mine flooded in northwestern Gansu province.
Xinhua says three others were lifted out of the facility in Jib city Sunday.
China has the world's worst mine safety record, with more than 2,600 coal miners killed last year in accidents and explosions.
