Officials said the army and relief workers were still battling to reach the worst-hit districts, where village after village were flattened when cyclone Sidr smashed into the disaster-prone nation overnight Thursday.
"We are expecting that thousands of dead bodies may be found within a few days," the deputy head of the government's disaster management office, Shekhar Chandra Das, told AFP in the capital Dhaka.
"We have not been able to collect information about casualties in many remote and impassable places due to the disruption to communications," he said.
In many areas, telephone lines are down and roads blocked.
The current confirmed death toll stood at 932. Countless more people have been injured or are homeless.
"We have got information that 932 bodies have been found and it is increasing still," said Home Ministry official Mohammad Salimullah.
People in Jhalokati, a town and district near the coast and one of the areas that bore the full brunt of the storm, told AFP
