According to Sirohi district collector LN Meena, a private bus coming from Nashik hit a truck while overtaking it.
“Drivers of both the vehicles entered into an argument in the middle of the road. Soon some young passengers got down from the bus to pacify them,” Mr Meena said.
Suddenly another truck coming from Sirohi side hit the truck from behind, which in turn ran over the passengers standing there killing nine of them on the spot. The rest of them later succumbed to their injuries, he said.

Those injured in the incident have been hospitalised in Udaipur, he said.
In the other incident, 13 people, including seven women and three children, were killed and 34 others were injured when a tractor-trolley collided with a truck late last night in Bhilwara district.
