VIDEO: At least 15 dead in Delhi stampede to catch trains to Kumbh mega-festival

At least 15 people died during a stampede at a railway station in India's capital late on Saturday when surging crowds scrambled to catch trains to the world's largest religious gathering, a medical official told AFP.

The Kumbh Mela attracts tens of millions of Hindu faithful every 12 years to the northern city of Prayagraj. Last month, at least 30 people died in another stampede at the holy confluence of the Ganges, Yamuna and the mythical Saraswati rivers.

The rush at the train station in New Delhi appeared to break out on Saturday as crowds struggled to board trains for the ongoing event, which will end on February 26.

"I can confirm 15 deaths at the hospital. They don't have any open injury. Most (likely died from) hypoxia or maybe some blunt injury but that would only be confirmed after an autopsy," Dr Ritu Saxena, deputy medical superintendent of Lok Nayak Hospital in New Delhi told AFP.

"There are also 11 others who are injured. Most of them are stable and have orthopaedic injuries," she said.

Defence minister Rajnath Singh said he was "extremely pained by the loss of lives due to stampede" at the New Delhi railway station.

"In this hour of grief, my thoughts are with the bereaved families. Praying for the speedy recovery of the injured," Singh said in a social media post.

The governor of the capital, Vinai Kumar Saxena, said disaster management personnel had been told to deploy and "all hospitals are in readiness to address related exigencies."

Railways minister Ashwini Vaishnaw said additional special trains were being run from New Delhi to clear the rush of devotees.

The six-week Kumbh Mela is the single biggest milestone on the Hindu religious calendar, and officials said around 500 million devotees have already visited the festival since it began last month.
