The Uttar Pradesh government has ordered a judicial probe into the deaths of at least 30 people in stampedes at India’s Kumbh Mela festival, where millions of Hindu devotees gathered for a ritual bath at the confluence of three sacred rivers.

A senior police officer said at least 30 people died as a crowd panicked at the Hindu Kumbh Mela mega-festival in the northern city of Prayagraj.

A barrier reportedly broke during a holy bath, injuring several devotees at the world's largest religious gathering.
