A deadly stampede interrupted the celebrations at a Hindu festival in northern India and left dozens of people dead. The Kumbh Mela, which is celebrated every 12 years, is the world’s largest religious gathering and draws upwards of 400 million pilgrims to the confluence of two rivers. According to Hindu belief, taking a dip in the river during this auspicious time can help wash away sins and free people from the cycle of rebirth.
