Now, officials in Bangladesh say a massive fire at a commercial building in the capital Dakar has killed at least 43 people. Reports said the blaze started at a restaurant and spread quickly through the building, trapping dozens of people. Now, let's get the latest from our South Asia Regional Editor, Anbarasan Eithi Rajan. What more can you tell us about what's happened?

Families are trying to find out what really happened to their loved ones who just went out on an evening to eat in a restaurant in Bayly Road, which is right in the heart of the capital, Dhaka, when this fire started trapping dozens of people. And this seven-story building housed clothing shops and several mobile phone shops as well. People suspect that the fire could have started in one of the restaurants because they all use cooking gas cylinders, and then it spread very rapidly through the building. One eyewitness was saying how in panic, people ran towards the rooftop and there was no emergency exit, which means they were really trapped because of this single staircase. And that was one of the reasons, according to one fire department official. Many people tried to come from the building because they could not get down and they were seriously injured. And according to the Health Minister, more than 40 people have been killed, and some of those injured are said to be in a critical condition. So people are really evaluating what It's not really happened. But the fire department official say now the fire has been brought under control.

I suppose the investigations are underway. Have authorities given more information about what they think may have caused the fire?

They are still investigating, but the suspicion is about the restaurants and some of those who were in the building, they were talking about how many cooking gas cylinders were left in the staircase itself. And that was one of the reasons why the fire spread so rapidly in this building. And many people are worried because they are... Some of those injured in the hospital, they were really affected by the smoke. And most of the victims were due to suffocation and smoke. And there are about 40 people in hospital. Now, the authorities are trying to find out what were the safety measures which are not followed by this building, whether this building had all the firefighting equipment or whether it had an emergency exit and why there was only one staircase, especially in a commercial building. So Bangladesh is not... It's not very uncommon in Bangladesh to have fired accidents because mostly they are blamed on lax safety rules.

Yeah, and Barisal, we're looking at live images outside the hospital where the victims have been taken. Quite a large crowd gathering outside. Stories like this you mention are not uncommon in Bangladesh. Is there going to be a loud outcry, do you think, from people there about another fire like this happening?

Well, every time when this incident happens, there was a lot of debate about what they should be doing because Dhaka itself is a densely populated city with very high-rise buildings, several residential and commercial buildings. Bangladesh is also home to one of the largest clothing factories. Ten years ago, there was a major fire at a clothing factory killing dozens. In fact, two years ago, in 2021, there was a major fire in a food processing factory killing more than 50 people. So they all blame on this lack of safety rules and how far the authorities are really serious about giving fire safety clearance to these commercial buildings, because first of all, they have to give this fire clearance so that these commercial buildings can operate. So people might question, how come this building was allowed to operate so many restaurants with cooking gas cylinders and without an emergency exit?

Questions will remain. Thanks very much. Bbc's South Regional Editor, Anbarasan Eithiraj on there.
