The incident happened when people were eating food in the open near the boundary wall, which fell on the people around 10 pm.
Superintendent of Police Anil Tank said the wall was nearly 90-feet long and 12-13 feet in height.
Several food stalls were set up adjoining the wall. A tin shed was also attached to a portion of the wall. “The injured were rushed to nearby hospitals immediately and treatment was administered. One injured has been referred for SMS Hospital in Jaipur,” he said.
District collector Narendra Kumar Gupta announced Rs 50,000 to each deceased family. Rs 10,000 would be given to the serious injured.
The bodies have been shifted to a mortuary and postmortem will be conducted on Thursday, a police source said.
Chief minister Vasundhara Raje condoled the deaths.
