Residents across huge swathes of northern China battled through choking pollution at extreme levels on Tuesday, as Beijing was plunged into toxic twilight for the fourth time this winter. Visibility was reduced to around 200 metres in parts of the capital, where mask-wearing pedestrians groped through a murky haze, despite warnings from authorities to stay indoors unless absolutely necessary.
