First it was smog, now it is fog. As winter descends, a cold fog blanketed northern India this week, obscuring the view of the Taj Mahal in Agra, about 200km from New Delhi.
Tourists seeking clear skies and sharp views have been frustrated by choking pollution in parts of northern India in recent weeks.

Air quality in Delhi plummeted after millions of people set off firecrackers to celebrate the Deepavali festival in October. That worsened the already serious pollution that was caused by the burning of crop stubble in neighbouring states.
