Eight people were killed and over 30 others injured after a double-decker bus crashed into another in the northern Indian state of Uttar Pradesh on Monday.
The accident occurred on the Purvanchal Expressway near Narayan Pur village in the state's Barabanki district, some 600 kms from the national capital.
Police said both the ill-fated buses were travelling to Delhi from the eastern Indian state of Bihar when the tragedy occurred.
"When one of the buses stopped suddenly in the middle of the high-speed corridor, the second one hit it from behind at cruise speed," a police officer told the local media.

The impact of the crash was such that eight passengers of the buses died on the spot, he said, adding that the injured were rushed to nearby hospitals.
Uttar Pradesh Chief Minister Yogi Adityanath took to social media to express his grief and extend condolences to the families of the deceased.
"A probe has been ordered into the crash," the police officer said.
Road accidents are common in India, with one taking place every four minutes. These accidents are blamed on poor roads, rash driving and scant regard for traffic laws.
The Indian government's implementation of stricter traffic laws in recent years has failed to rein in accidents, which claim over 100,000 lives every year.
