Two killed in 'devastating' New York building collapse

At least two people have been killed after a "devastating" building collapse in Brooklyn, New York City's mayor has said.

Zohran Mamdani said fire crews responded within one minute of the first 911 call.

Footage from news helicopters showed hundreds of rescuers scouring debris for survivors - and appearing to use a saw to cut through the wreckage.

"This has been an incredibly challenging and fast-moving situation - with precarious wreckage to navigate and dangerous voids beneath the surface," Mr Mamdani said.

Crews were seen pulling someone from the rubble of the three-storey building and placing them on a stretcher, passing them carefully from person to person.

Four of the injured are in a critical condition.

More than 250 firefighters were deployed to the scene - and it is unclear how many people remain trapped.

New York City fire commissioner Lillian Bonsignore said: "This will be a prolonged operation. Its cause is under investigation. Currently - and this is subject to change - we have 19 patients."

Seven children and a firefighter were among those hurt.

Mr Mamdani added: "I want to ask New Yorkers to please take a moment to pray for those who passed away today and all of those who are mourning their loss, as well as for a fast and full recovery for all those who were injured."

The collapse happened close to where another structure had been torn down for a construction project.

A building that shared a wall with the collapsed property remains standing but exposed - exposing bedrooms and closets filled with clothing.

As darkness fell, crews deployed sniffer dogs and used flashlights to illuminate the area where they worked.

"The units are proposing dangerous and heroic work," Ms Bonsignore said.
