Eleven people were killed and over 50 were injured on Sunday evening after two state-run transport buses collided in Tamil Nadu’s Sivaganga district, The Hindu reported.

The crash occurred around 5 pm near Vivekananda Polytechnic College on the Tirupattur-Karaikudi road. One bus had been travelling from Kangeyam towards Karaikudi and the other was operating on the Karaikudi to Dindigul route when they collided, the police said.

“Eight people died on the spot,” an unidentified officer told The Indian Express. “Three more succumbed to injuries at the Tirupattur Government Hospital.”

Among those who died on the spot was the driver of one of the buses, P Sendrayan, according to the police.

The injured were taken to hospitals in Karaikudi, Thirupattur, Sivaganga and Pudukottai. Six of them were referred to the Government Rajaji Hospital in Madurai, The Hindu reported.

Initial inquiries indicate that both buses may have been travelling at high speed on a narrow stretch of the road.

The police have filed a case and are investigating the cause of the accident.

Chief Minister MK Stalin expressed his condolences and announced compensation of Rs 3 lakh for the families of those killed, Rs 1 lakh for passengers with serious injuries and Rs 50,000 for those with minor injuries.
