Beijing is shrouded in orange dust from a sandstorm originating from drought-struck northern China hundreds of miles away.
The authorities have issued a level-five pollution warning and urged people to stay indoors.
In Tiananmen Square, clouds of dust obscured monuments and visitors wore masks to avoid the dust and soil.
The storm has already caused havoc in Xinjiang, Shanxi, Shaanxi and Hebei regions and is heading to South Korea.
