A strong gust of wind sent two workers on a high rise flying until they rammed into windows and died, local newspaper hsw.cn reports on July 25, 2015.

The incident happened late Friday at a high-rise building in downtown Xi'an, the capital of northwest China's Shaanxi Province.

A witness surnamed Liu says the two workers first cried for help but after struggling in the strong wind for more than twenty minutes, they crashed into the windows and died.

The windows the two workers rammed into are said to be on the 12th and 15th floors.

The company responsible for constructing the building has not responded.
