Lucknow: At least six people were killed and around 25 injured when a bus rammed into a stationary car on the Agra-Lucknow Expressway in the district on Sunday, an official said.

The bus was carrying around 45 labourers from Bihar's Madhubani district to Delhi, Sub-Divisional Magistrate, Chhibramau, Gaurav Shukla, said.

Both the vehicles overturned and fell off the expressway.

The accident occurred at around 5:15am 122 kilometres from the state capital of Lucknow. The bus, according to police, had started from Darbhanga in Bihar and was going to Delhi.

“A private bus with around 40 passengers toppled down the highway after colliding with a stranded SUV. Five passengers were killed on the spot while another died minutes after reaching the hospital,” Amrendra PD Singh, Kannauj’s superintendent of police (SP), said.

“Around 20 other passengers have also sustained injuries. They have been admitted to hospital,” Singh added.

The driver of the bus is among the five deceased. Locals rushed to the spot and helped police evacuate trapped passengers.

The injured passengers have been admitted to hospitals in Saurikh and Saifai. Condition of some of the injured is said to be critical.

“It appears that the bus driver failed to spot the SUV in time that led to the collision and then failed to control the bus which toppled down,” Singh said.

Uttar Pradesh chief minister Yogi Adityanath has expressed grief over the loss of lives in the accident and instructed officials to ensure proper treatment for those injured.
