On the 16th of March 2020, the Rupnagar slum in Mirpur of Dhaka city in Bangladesh caught fire. Hundreds of houses were burnt down and thousands of people were left injured, homeless and without food.
This is the time, I worked with a local volunteer group called "Protyasha'r Alo" to provide food and clothing to the devastated families of the slum. 
We worked continually for 3 days and provided food, clothing and basic medical supplies (pain killers and saline) to about 500 families within the slum. We also tried to help them to rehabilitate themsleves.
