Diwali, the festival of lights, was celebrated with traditional fervour across the country with people exchanging sweets and gifts with friends and relatives, decking up their houses with earthen diyas and tiny lights and illuminating the evening sky with fireworks.
Children and youths burst crackers and lit sparklers while families, dressed up in their best outfits, visited their neighbours, exchanged 'Happy Diwali' greetings and sweets.
