'Ambulances zipping past': BBC reporter at site of crowd surge in India
Many people are feared to have been killed following a crush at the Kumbh Mela, the world's largest religious gathering being held in the northern Indian city of Prayagraj.
The BBC's Vikas Pandey, who is at the scene, described seeing many ambulances zipping past.
There is no confirmation yet on how many people may have been injured or killed. One official said earlier that "some people have been injured" - but added that "no-one is serious."
Held every 12 years, the Kumbh is often called the world's largest gathering of humanity, and Wednesday is the biggest day of the festival. Officials have said up to 100 million people are expected to attend the bathing day.
