Thick smog blanketed Beijing for a second day yesterday, putting the city on a higher air pollution alert and forcing its dirtiest factories to cut fumes by 30 per cent.

The capital raised its pollution alert from yellow to orange - the second-highest level on a four-tier warning system - at about noon, with the contamination remaining hazardous throughout the day.

Beijing's official Air Quality Index reached 470 at 4pm. A reading of over 300 is considered severe pollution.

Toxic smog also blanketed nearby cities - mostly in Hebei and Shanxi provinces - including Xingtai , Shijiazhuang , Dingzhou and Yangquan . Eighteen highways linking Beijing, Harbin and Shanghai had to be closed, according to the China Meteorological Administration.
