One herdsman has been injured after fires broke out on the grasslands in north China's Inner Mongolia Autonomous Region on Tuesday and Wednesday, said fire fighting sources.

The first fire to hit East Ujimqin Banner took more than 300 fire fighters seven hours to put out. A female herder was injured fighting the fire and was sent to hospital for treatment.

A second fire broke out in the same banner at midday Wednesday. More than 300 people have been mobilized. Herders and livestock threatened by the fire have been evacuated.

Fire fighting efforts are continuing despite windy and dusty weather.

The causes of the fires were unclear.
