A deadly blaze has killed dozens of people in the historic district of Chawkbazar in the Bangladeshi capital of Dhaka. But as BBC Bengali's Rakib Hasnet reports, it is not the first time the area has seen tragedy.
It was on the banks of the Buriganga River during the Mughal dynasty, some 400 years ago, that Chawkbazar was established. It quickly became the main business hub of Dhaka.
Until just a few decades ago, Chawkbazar, inside Old Dhaka, still had a reputation as the heart of the city. But as Dhaka grew bigger and bigger, becoming a sprawling urban metropolis, the importance of Chawkbazar as a commercial hub diminished.
It remains popular, though.
Today, Chawkbazar is a hub of businesses making and storing chemicals, perfume and plastic products, many ignoring a ban on the storage of chemical goods in residential buildings.
A deadly fire in 2010 in another part of Old Dhaka killed 120 people. However, ground floors in residential buildings still serve as warehouses for chemicals, gas cylinders and plastic products.
