Fossiar Rahman, a resident of Kalia municipality, said Nazma Begum along with her son was going to her father's place in Bahirdanga village. The accident might have taken place due to overloading.
"We are conducting a search and rescue operation for the missing passengers," said OC Tasmeem, adding that the bodies will be handed over to their families after due process.
