BEIJING – Fog and pollution in northern China have led to flight cancellations and road closures during a peak travel period as a weeklong national holiday nears its end.
China's National Meteorological Center said the haze would hang over a large area of northern China until Monday afternoon. It said that in some areas of Beijing visibility had dropped to less than 500 meters (yards) on Saturday night and Sunday morning.
State media reported six major expressways had partly closed, including one linking Beijing and Shanghai.
Beijing Capital International Airport said four international flights had been cancelled Sunday morning while three had been delayed. Two domestic flights were cancelled and 20 delayed.
Hundreds of millions of Chinese travel during the Oct. 1-7 holiday known as Golden Week.
