More than seven people were killed in a stampede at the Maha Kumbh Mela, or Great Pitcher Festival, in the northern Indian holy city of Prayagraj on Wednesday.

According to the Indian government, some 400 million people were expected to attend the Maha Kumbh Mela, the most important religious event in Hinduism, held this year in Prayagraj from January 13 to February 26.

Eyewitnesses and hospital sources have told the BBC that at least a dozen people have been killed in Wednesday morning's crush at the Kumbh Mela festival in Prayagraj. There is, however, still no word from the government on what happened or the number of casualties.

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.

Indian Prime Minister Narendra Modi attended on Wednesday the Hindu festival Kumbh Mela in northern India and immersed himself in the confluence of the sacred Ganges and Yamuna rivers, where a stampede claimed the lives of 30 people and left nearly a hundred injured a week ago.
