An Indian Hindu devotee pours milk on a snake as an offering during the annual Nag Panchami festival, dedicated to the worship of snakes outside the Nagvasuki temple, in Allahabad, on July 28, 2017. Officially the snake charmers' profession is banned in India, but many in the country offered prayers and milk blessings to cobras and other deadly serpents on July 28 in an annual tribute.
