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.

PRAYAGRAJ, India — At least 30 people were killed and many more injured in a stampede at the world’s largest religious gathering early Wednesday, police said, as millions of pilgrims rushed to dip in sacred waters during the Maha Kumbh festival in northern India.

Moments before a deadly stampede at the world's biggest religious gathering in India, Hindu devotees queuing to take a spiritual bath in a river said they pleaded with police to open barricaded routes to thin out a surging crowd.
