In this photo by Rajesh Kumar Singh, police on horses patrol as thousands of Hindus perform rituals at the Sangam, the confluence of the Ganges, Yamuna, and the mythical Saraswati rivers, during the Magh Mela in Allahabad, India. Hundreds of thousands of pilgrims will bathe in the confluence during the annual festival, hoping to wash away their sins. Monday is the morning of the new moon, or "Mauni Amavasya," the most auspicious and most popular day for the ritual.
