Diwali

India's streets and homes are lit up with colourful lanterns and glowing lamps as millions celebrate the Hindu festival of Diwali. But the celebrations are also sparking concerns about air pollution, including in the national capital, Delhi. A time for feasts, prayers and fireworks, Diwali is one of the most important festivals in India. It is known as the festival of lights as people illuminate oil lamps or candles to symbolise the triumph of light over darkness and good over evil. People illuminate their homes with oil lamps and draw rangolis - traditional designs made using colourful powders - outside their doors to welcome good luck and positivity into their lives. Families gather to offer prayers, light fireworks and enjoy festive meals. People visit friends and family and exchange sweets, gifts and good wishes.
