The Kumbh Mela festival, the largest religious gathering in the world, has begun in the northern Indian city of Prayagraj.

Days before India started its mammoth Kumbh Mela festival, a video showing preparations for a nighttime light show surfaced in social media posts that falsely linked it to the six-week Hindu event. The video was in fact originally published by a US-based drone show company and shows a Christmas celebration.

An estimated 40 crore people are expected to attend the Maha Kumbh in Prayagraj this year with the Uttar Pradesh government earmarking a budget of Rs 6,990 crore for the gathering.
