"I've spoken to the Commissioner of Varanasi who apprised me of the situation. I also asked the Varanasi Commissioner to provide all possible help to those affected by the tragedy," he told reporters after inaugurating a 10-day 'Rashtriya Sanskriti Mahotsav' here.
"There have been loss of lives and people have been injured also. It is a sad incident," Singh said.
Meanwhile, Tourism Minister Mahesh Sharma said the incident "indicates the mis-management" of the arrangements for the event and expressed the need to fix responsibility.
The stampede took place at Rajghat bridge Varanasi- Chandauli border when thousands of followers of religious leader Jai Gurudev were on their way to Domri village on the banks of the Ganga to take part in a two-day camp.
Officials said 24 persons were killed in the stampede.
