At least 5,000 people were homeless after the powerful twister turned four villages into rubble in the border district of Brahmanbaria, 250 kilometres east of the capital Dhaka.
An earlier report said 20 people were killed and a hundred other injured in Monday's tornado that had left a trail of devastation.
The tornado destroyed homes, uprooted power poles and brought down trees besides damaging summer rice crops.
Ten of the dead are children who were killed under collapsing roofs of their huts. Four women were crushed to death in a fruit orchard by toppled mango trees, witnesses said.
Rescue workers said the death toll could rise as medical help and emergency food supply could not be reached to all stricken hamlets due to uprooted vegetation and other debris blocking roads.
