Meanwhile, Diwali was celebrated with great fervour, gaiety and enthusiasm in Haryana and Punjab on Thursday. Candles, diyas (earthen lamps) and electric lights dotted houses as people exchanged sweets and gifts on the occasion and burst firecrackers.

The authorities granted permission to burn only "green crackers" for a restricted period of time on Diwali day.

In Chandigarh, the twin capital of Punjab and Haryana, use of only green crackers was allowed within a designated time limit between 8 pm and 10 pm.

However, in many parts of Chandigarh, people continued to burst firecrackers well past the 10 pm limit.

The Punjab government recently said that only green firecrackers will be allowed during festival celebrations for Diwali, Gurpurab, Christmas and New Year's eve.

Only green crackers, which are free from barium salts or compounds of antimony, lithium, mercury, arsenic, lead or strontium chromate, were permitted for sale and use in Punjab, an official statement released earlier said.
