Multiple people were feared dead in a crowd crush at the world’s largest religious festival in India Wednesday, as tens of millions of devotees went to bathe in a river on one of the most sacred days of the Hindu festival.

More than seven people were killed in a stampede at the Maha Kumbh Mela, or Great Pitcher Festival, in the northern Indian holy city of Prayagraj on Wednesday.

Being held after 12 years, the Maha Kumbh kicked off on January 13 and will continue till February 26. The UP government, hosting the fair, expects a total footfall of around 40 crore pilgrims at the largest spiritual gathering on the planet.
