At least 10,000 people are homeless after a massive fire swept through a crowded slum in the Bangladesh capital and destroyed thousands of shanties, officials said Sunday.

The fire broke out in Dhaka's Mirpur neighborhood late on Friday and razed around 2,000 mostly tin shacks, fire services official Ershad Hossain told AFP.

"I could not salvage a single thing. I don't know what will I do," 58-year-old Abdul Hamid, who ran a tea stall inside the slum, told AFP as he broke down in tears.

Authorities eventually got the blaze under control and no one was killed, although several people had minor injuries, firefighters said.

Many residents were not in the slum as they had left their homes to celebrate the Muslim Eid al-Adha holiday with their families.

"Otherwise, the damage would have been bigger," local police chief Golam Rabbani said.

Around 10,000 people have taken refuge in crammed camps at nearby schools closed for the week-long holiday, according to Hossain.

"We are providing them with food, water, mobile toilets, and electricity supply," municipal official Shafiul Azam told AFP.

Some families have erected tarpaulins to shelter them from bouts of rain during the monsoon season, but the wet conditions have turned the fields muddy.
