At least 30 people died and several were injured in a crush at the religious festival in India this week.

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

A massive Hindu religious festival turned deadly Wednesday when at least 39 people were killed during a crowd stampede. Police reported that at least 90 people were hurt at the Maha Kumbh Mela festival in northern India.

The Kumbh Mela happens every 12 years at Sangam, the confluence of three sacred rivers - the Ganges (Ganga), Yamuna and the mythical Saraswati. Hindus believe that bathing in the sacred waters will cleanse them of sins and help them attain salvation.
