More than 8,300 people are helping to fight a huge forest fire in northern China, according to media reports. The blaze in Daxing’anling prefecture in Inner Mongolia has spread to over 5,000 hectares with two fronts of the blaze each stretching about 7km, the reports said. It is the second large forest fire to hit the area over the past few days amid higher temperatures and dry conditions in the region this spring. 1,345 Chinese firefighters tackle blaze that spread from Russia High winds have also contributed to the spread of the blaze. The fire started at about noon on Tuesday, although the cause is not clear, the Shanghai-based website Thepaper.cn reported. Daxing’anling is a mountainous forested area and the State Forestry Administration said a sudden change in the direction and force of the wind had spread the fire quickly to the southwest, putting firefighters in “extreme danger” and severely hampering efforts to put out the blaze.
