The incident occurred on a bridge over the Sindh River while pilgrims were headed to the temple for a Hindu festival.
“The death toll could go much higher as about 25,000 people were present on the bridge at that time,” said D.K. Arya, a local deputy police inspector.
A rumor that the bridge was about to collapse caused panicked people to stampede, police told CNN sister network CNN-IBN.
Many people jumped off the bridge into the river, Arya said.
The stampede occurred at a temple in the central state of Madhya Pradesh.
