Beijing's 2nd Smog Red Alert of the Month
Beijing was enveloped in eye-watering, throat-irritating smog on Saturday as the second red alert of the month went into effect in the Chinese capital, forcing many cars off the roads and restricting factory production.
A wave of smog settled over the notoriously polluted city of 22.5 million overnight and is forecast to last into Tuesday because of a lack of strong winds.
Smog red alerts, the most serious in a four-tier warning system, are triggered when high pollution levels are forecast to last more than 72 hours.
As a result of the red alert, schools were ordered closed and half the city's cars forced off the roads each day. Barbecue grills and other outdoor smoke sources have been banned and factory production restricted.
