No deaths have been reported so far after the blaze set at least 10 square km of woods on fire and continued to burn due to strong winds.

The fire was discovered at around 2 p.m. Thursday on Changxing Island, a new economic and technological development zone in Dalian.

The cause of the fire is not yet known.
