More than 10 million devout Hindus seeking absolution from their sins took a dip in holy waters in northern India during a span of four hours on Wednesday, authorities said, as they braced for millions more to swarm the site of the Kumbh Mela.

A video spread online shows an annual stone-pelting ritual in northern India, contrary to claims by social media posts that presented it as Hindu pilgrims attacking each other at the Kumbh Mela mega-festival.

As the Amrit Snan began at the ongoing Maha Kumbh Mela on Maghi Purnima on Wednesday morning, lakhs of people reached the Triveni Sangam ghat in Prayagraj to take the holy dip on the special occasion.

India's Kumbh Mela festival attracts tens of millions of Hindu faithful to Prayagraj in northern Uttar Pradesh state, but footage of an elderly monk making an offering at a shrine that circulated online is unrelated.

Arunachal Pradesh Governor Lt. General KT Parnaik (Retd.) and First Lady Anagha Parnaik visited Prayagraj as part of a four-day trip to Uttar Pradesh, engaging in key religious and cultural activities.

President Droupadi Murmu took a holy dip at the Triveni Sangam here on Monday and said the huge gathering of faith and belief at the Maha Kumbh is a living symbol of India's rich cultural heritage
