DHAKA: A fire broke out in a 22-storey commercial building in the Bangladeshi capital, Dhaka, on Thursday, killing at least five people, including a Sri Lankan, injuring at least 60 and trapping many, officials said.

Some of those trapped waved frantically from the building’s windows and roof while others tried to jump to safety. Fire fighters perched on cranes smashed windows in an attempt to reach those inside, witnesses said.

Hundreds of people gathered to watch in the street below. One man who tried to escape by descending from a rope fell, a Reuters witness said.

The building is in the upscale, built-up Banani area of the city and the cause of the fire was not immediately clear. A girl sobbing outside the building said her father worked in an office inside and he was not answering his phone.

"I don't know where he is," she said.

The blaze comes a month after a massive inferno killed 71 people in an old neighbourhood of the city. Critics at the time blamed poor enforcement of safety regulations in one of the world's most densely packed cities.

Helicopters joined 22 firefighting units that worked with the army, navy, air force and police to battle Thursday's blaze as smoke billowed into the sky.

"The fire is almost under control,” said Mizanur Rahman, a senior fire service official at the scene.

Several of the roughly 140 employees of the private firm Quasem Group that had multiple offices in the building, escaped across a roof to an adjacent building, said Shamim Reza Khan, an assistant general manager at the firm.

Nanda, a finance manager at the IT firm AAMRA which has offices on four different floors in the building, said he escaped with 20 colleagues.

DHAKA: A fire broke out on Thursday at a high-rise building in a commercial area of the Bangladeshi capital, trapping many people and prompting some to jump to safety, police and fire officials said.

More than a dozen people were injured and fire trucks were trying to douse the fire in the Banani area of Dhaka, where the building is located, among many structures close together.

"We have sent them to various hospitals," said Enayet Hossain, a senior fire official, referring to the injured. "More than a dozen fire tenders are at the spot."

Last month, a massive fire killed 71 people in an old neighbourhood of the congested city.
