Indian Hindu devotees bathe on Gangasagar Island some 150 kms south of Kolkata on January 13, 2018.
More than 700,000 Hindu pilgrims and sadhus - holy men - are expected to gather at the confluence of the River Ganges and the Bay of Bengal during the Gangasagar Mela, to mark Makar Sankranti, a holy day of the Hindu calendar considered to be of great religious significance in Hindu mythology.
