A vermilion dot on the forehead is one of India’s most widely accepted Hindu cultural insignias. But at the festival, where millions are flocking to pray and bathe at the confluence of India’s holy rivers, it morphs into a major display of Hinduism in various forms and designs.

More than seven people were killed and around 10 injured in a stampede at the Maha Kumbh Mela in northern India on Wednesday, said an official, as tens of millions gathered to take a holy dip on the most auspicious day of the six-week Hindu festival.

At least 30 people were killed and over 30 have been injured in a stampede at the Maha Kumbh Mela, one of the world's biggest gatherings that occurs every 12 years.
