Mandsaur: In a tragic incident in Madhya Pradesh's Mandsaur district on Sunday, a speeding van collided with a bike and plunged into a water-filled well, resulting in the deaths of 11 people, including the biker and a rescuer

The incident happened in the Narayangarh police station area.

Ratlam range Deputy Inspector General (DIG) Manoj Singh said 13 persons were travelling in the van.

"Four of them were rescued while nine others died. A villager, identified as Manohar, who descended into the well for rescue, also died," he said, adding that the body of a victim of the accident is yet to be pulled out of the well.

Deputy Chief Minister Jagdish Devda, who rushed to the site, said the driver apparently lost control of the van, which then veered off the road and fell into a well.

A rescue operation, involving the National Disaster Response Force (NDRF) and personnel of other units, is underway.
