Six people, including four of a family, were killed when a tempo they were travelling in was hit by a tractor in the Mujaria area here Thursday morning, police said.
Five injured were rushed to the district hospital.
The party was returning home to celebrate Diwali.
The victims, who worked as vegetable vendors in Noida, were travelling in a three-wheeled loader tempo which collided with a tractor-trolley.
A speeding car then struck the loader, making the chance of an escape even narrower.
Atul, 31, from Mirzapur, Kanhai, 35, from Bareilly, his wife 30-year-old Kusum, and their children, Kartik and Sheenu, aged eight and five, died in the collision, according to Budaun District Magistrate Nidhi Srivastav.
The sixth deceased is yet to be identified, she said.
A search is on for the tractor driver who fled after the incident.
Netra Pal Singh, a local resident who witnessed the accident, said, "The impact of the collision was so severe that several passengers were thrown out of the vehicle." Kanhaiya and his wife Kusum were travelling to their village, Kunwargaon, to celebrate Diwali, said Santosh Kumar, a relative of the couple.
Kaptan Singh, a survivor who sustained multiple injuries, said he remembered only a little of what came in the wake of the collision.
"I was sitting in the loader and had myself covered with a jacket. I saw the tractor that hit our loader. That was the last thing I remember. I lost my consciousness and woke up in a hospital," he said.
Chief Minister Yogi Adityanath offered his condolences to the kin of the deceased and ordered proper treatment of the wounded.
