Two ferries with passengers on board are stranded in the middle of the Padma river as dense winter fog has forced authorities to halt services on the Daulatdia-Paturia route.
Md Khaled Newaz, a deputy general manager with Bangladesh Inland Water Transport Authority, said they suspended the services around 9:30pm on Saturday as visibility fell to zero.
The ferries Rajanigandha and Faridpur were stranded mid-river at that time, he said.
Some vehicles were also stranded in the piers, said the BIWTA official.
The authorities could not confirm when the services would resume.
