Over three crore people gathered in Allahabad on Sunday to take a holy dip on the occasion of 'Mauni Amavasya' - considered the most auspicious day during the 12-yearly congregation.
Railway Minister PK Bansal said that he has been told that around 10 people have died so far.
The ritual of bathing started on Saturday afternoon itself when 'Mauni Amavasya' began according to the Hindu almanac and reached its crescendo on Sunday morning.
Tight security arrangements were in place with more than 15,000 security personnel drawn from central paramilitary forces like ITBP, CRPF, BSF and RAF besides the UP Police.
According to sources, 2 lakh people were present at the railway station at the time of stampede.
According to eyewitnesses, no doctor or ambulance came for more than two hours.
There are reports of a lathicharge which compounded the tragedy.
A railway station in the neighbouring district of Pratapgarh was vandalised on Sunday morning by people angry over non-availability of a special train for a trip to the holy Sangam.
The stampede was caused after railing of an over bridge at the railway station collapsed.
Following the stampede, Uttar Pradesh Chief Minister Akhilesh Yadav announced a committee which will probe into the incident.
Condoling the incident, Prime Minister Manmohan Singh instructed the Union Railway Ministry to provide all possible assistance to the Uttar Pradesh government in managing the incident.
