Eleven of a family, among them five women and two children, were killed when a jeep and a dumper collided head on in Madhya Pradesh's Ujjain district, a police official said.
Those killed were travelling in the jeep. Angered over the deaths, which virtually wiped out a family, a mob set the dumper on fire.
The accident occurred on Ujjain-Aagar Malwa road near Palwa village. All the 11 were killed on the spot while one person was left seriously injured. All of them belonged to Mahidpur, the Ujjain police superintendent told IANS, confirming the toll.
