The trailer was carrying about 40 people, mostly women and children, in the city of Kanpur in the state of Uttar Pradesh.
A farm tractor trailer carrying Hindu pilgrims overturned and fell into a lake in Ghatampur, in the northern Indian city of Kanpur, killing 26 people, mostly women and children, officials said on Sunday.
Kanpur Superintendent of Police Tej Swaroop Singh said the wagon was returning with about 40 people from a ceremony at a nearby Hindu temple on Saturday night. He said most of the deaths were due to drowning.
At least 10 people were injured in the accident in Kanpur, about 100 km (60 miles) southwest of Lucknow, the capital of Uttar Pradesh state. The injured have been admitted to the hospital.
The cause of the accident is still under investigation.
Prime Minister Narendra Modi expressed condolences.
“Distressed over tractor-trolley accident in Kanpur. My thoughts are with all those who have lost their near and dear ones and pray for the injured,” Modi tweeted.
This is the second incident in Uttar Pradesh in the last week – a tractor carrying people overturned on Monday, killing at least 10 people.
Uttar Pradesh’s top elected official, Yogi Adityanath, discouraged the use of farm tractors for passenger transport.
“Tractor-trolleys should be used for agricultural work and transporting goods, not for transporting people,” he said in a statement.
Traffic accidents are frequent in India, killing more than 150,000 people last year or killing more than 400 people, according to official figures which may be underestimated.
