The pilgrims were riding on the flatbed trailer pulled by a farm tractor on their way to a temple to mark the Hindu festival of Janashtami, the traditional anniversary of Lord Krishna´s birth, Lal said.
The vehicle was carrying more than 60 passengers, most of them women and children, he said. Most of the victims drowned.
