The national flag flew at half-mast thousands of people joined in prayers Saturday as Bangladesh mourned the deaths of nearly 120 people in the country's worst fire.
Special prayers were being held in mosques, temples and churches across the Muslim-majority country, and Bangladesh's green and red flag fluttered at half-mast as part of a day of national mourning.
Television channels suspended their normal programmes and were airing sombre religious songs and prayers.
The country's deadliest blaze in recent memory broke out Thursday night in the narrow alleys of the old section of Dhaka, when an electrical transformer exploded soon after a rainstorm swept the city. About 117 people were killed and 100 others were injured.
Firefighters are blaming a chemical warehouse for helping accelerate the blaze. The area in the old part of Dhaka has many chemical warehouses or small factories in residential neighborhoods.
Dhaka's police chief A.K.M. Shahidul Haque said authorities are working to evict chemical shops or warehouses from the area.
Meanwhile Saturday, panicked residents fled one of Dhaka's tallest buildings after large cracks appeared in the 22-storey block of apartments and offices.
Local police chief Shahidul Haque said "people are scared and nervous" following the deadly blaze and the collapse of a four-story building this week that together claimed nearly 150 lives.
Thursday's fire began when an electrical transformer exploded, with the flames spreading rapidly to a warehouse next door which was illegally storing powerful glue used to manufacture shoes.
Firefighters were searching for bodies in the charred and twisted remains of six apartment buildings again on Saturday.
Prime Minister Sheikh Hasina has visited the injured and announced compensation and free treatment for the victims.
