A powerful tornado ripped through over a dozen rural villages in Bangladesh's Brahmanbaria district, killing at least 23 people.
One local newspaper had the number injured at close to 500 but government officials could not confirm that number.
The injured have been flowing in from cities including the capital Dhaka, close to 100 km away.
One official said up to 12 people were in critical condition.
On Saturday, local chief government administrator Noor Mohammad Majumder said the death toll had climbed to 23 people, with another 200 injured in the powerful storm.
The local Prothom Alo newspaper reported that the 15-minute storm destroyed many homes and shops, and toppled a large number of trees and electricity poles.
Bangladesh is prone to deadly storms and tornadoes between March and mid-May, just before the beginning of monsoon season.
