Thousands of people at a religious gathering in India rushed to leave a makeshift tent, setting off a stampede Tuesday that killed more than 100 and left scores injured, officials said, Paralel.Az reports citing ABC News.

It was not immediately clear what triggered the panic following an event with a Hindu guru known locally as Bhole Baba. Local news reports cited authorities who said heat and suffocation in the tent could have been a factor. Video of the aftermath showed the structure appeared to have collapsed.

At least 116 people died, most of them women and children, said Prashant Kumar, the director-general of police in northern India's state of Uttar Pradesh, where the stampede occurred.

More than 80 others were injured and admitted to hospitals, senior police officer Shalabh Mathur said.

“People started falling one upon another, one upon another. Those who were crushed died. People there pulled them out,” witness Shakuntala Devi told the Press Trust of India news agency.
