Chinese city shrouded in smog—airport shut down, masks are being worn, and ground transport is at a standstill.. 

And because of the smog, and God knows what’s in the thick stew, a city of 11 million people in China has completely been cut off from the world

This is London today, along with many other places in the UK, where thick smog has descended on the continent.. Health officials have said those with asthma or breathing problems should avoid the air and stay indoors.. Also:  Don’t exercise outdoors.. This as the thick layer of pre-Easter heat and smog descends on London.
