A senior police officer said at least 30 people died as a crowd panicked at the Hindu Kumbh Mela mega-festival in the northern city of Prayagraj.

Millions of devout Hindus thronged the northern Indian city of Prayagraj on Thursday for the Maha Kumbh festival, a day after dozens died in a stampede on the most auspicious day of the six-week event.

People were trampled as pilgrims at the Maha Kumbh Mela, one of the world’s biggest gatherings, gathered where the Ganges and Yamuna Rivers meet.
