The truck fell into a drain in Gujarat's Bhavnagar.
At least 26 people from a wedding party were killed and 12 injured after a truck carrying them plunged off a bridge in Gujarat's Bhavnagar district early morning on Tuesday.
The injured victims have been rushed to a local hospital. Rescue teams have reached the accident spot.
Around 60 people were on board the truck and most of the victims were women and children, Gujarat police inspector KJ Kadapda told AFP.
The driver lost control causing the truck to swerve off the bridge and fall eight metres (26 feet) onto a dry riverbed in Gujarat state, police said.
The truck overturned and officials indicated the toll could rise as many of the passengers remained trapped under the truck.
