Cows and buffalos are seen outside a dairy on the outskirts of the Indian capital New Delhi on April 26, 2017. India could issue millions of cows with unique identification numbers, the latest effort to protect the sacred animals amid a spike in violence by Hindu vigilantes against farmers accused of cattle smuggling. The government has told the Supreme Court that millions of cows will be tagged with a tamper-proof plastic tag linked to a national database in a bid to curb smuggling within India and beyond its borders. / AFP PHOTO / Prakash SINGH
