Indian Prime Minister Narendra Modi took holy dips in sacred river waters in the northern city of Prayagraj on Wednesday as he joined millions of people at the Maha Kumbh Mela, a week after dozens died in a stampede at the event.

At least 17 people were killed and many more injured in a stampede at India's Maha Kumbh festival, the world's largest religious gathering, a doctor at a government hospital said, as tens of thousands of pilgrims rushed to dip in sacred river waters during the Hindu event.

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.

It was not immediately clear what triggered the panic at the festival where devotees from across India had congregated to bathe at the confluence of the Ganges, the Yamuna and the mythical Saraswati rivers.

Prime Minister Narendra Modi on Wednesday took a holy dip at the Triveni Sangam and said he felt "blessed to be at the Maha Kumbh" where he was "filled with a spirit of devotion"
