Ferry services on the Paturia-Daulatdia route have been halted early Friday due to the dense fog.
The ferry service suspended around 4am today, Assistant General Manager of Paturia Nasir Hossain said.
He said: "Ferry movement was suspended around 4am to avoid any untoward incident. The services will resume once the fog is cleared."
Twelve ferries were stranded on both sides of the river Padma, the BIWTC official added.
Several other ferries with passengers and vehicles remained stuck in the middle river, Paturia and Daulatdia ferry ghats for hours.
Long queues of vehicles were seen on both sides of the river.
