Business leaders in Bangladesh fear losses of more than $1bn (£750m) after a devastating fire broke out in the logistics section of the country's main airport on Saturday.

Clothes and raw materials were among the goods destroyed, which could put some businesses at risk, according to the country's export associations.

The cause of the fire - which took 27 hours to extinguish - is still being investigated. The blaze had forced the temporary suspension of flights and airport operations.

Bangladesh is the word's second-largest exporter of clothes after China, supplying global retailers like H&M and Walmart.

Bangladesh's garment sector generates around $40bn a year, accounting for over a tenth of its gross domestic product.
