At least 116 people have been killed in a crush at a religious gathering in northern India, police inspector Gen Shalabh Mathur has said.
The incident took place at a satsang (a Hindu religious event) in Hathras district in Uttar Pradesh state.
The victims, including a large number of women and some children, are still being identified.
Survivors have described how the disaster unfolded as they tried to leave the event in Mughalgarhi village.
It is not yet clear what led to the crush. Witnesses said the exit was too narrow and when people were leaving, a fierce dust storm led to confusion and panic, causing many people to become trampled.
An eyewitness, who asked to remain anonymous, told the BBC everything was “going fine”, until “all of a sudden I heard screams and before I knew it, people were falling on each other”.
“Many were crushed and I couldn’t do much. I am just lucky to have survived.”
“When the sermon finished, everyone started running out,” a woman named only as Shakuntala told the Press Trust of India news agency.
“People fell in a drain by the road. They started falling one on top of the other and got crushed to death.”
Umesh Kumar Tripathi, chief medical officer from the neighbouring district of Etah, told reporters the “stampede” had left at least three children dead.
A spokesperson for a senior police officer in Uttar Pradesh told the BBC it would “take hours to release the final tally”.
Distressing images from the site are being circulated online. Some videos showed the injured being taken to hospitals in pick-up trucks, tuk tuks and even motorbikes.
Mr Kumar said the venue had been overcrowded, adding that a high-level committee had been formed to investigate the incident.
“The primary focus of the administration is to provide all possible help to the injured and kin of the deceased,” he said.
