Campaigners in India are pushing to introduce anti-racism legislation after the recent killing in Delhi of a college student.

Nido Tania, 19, came from north-east India and was beaten by shopkeepers who had ridiculed his appearance. He died the next day.

Indigenous people from the north-east are ethnically closer to Burmese and Chinese people, and many report racism and discrimination in the rest of the country.

Protesters say India's existing anti-discrimination laws are not enough to tackle racist hate crimes.
