I joined @fdny and emergency crews at the scene of today's tragic building collapse on Flatbush Avenue. Two of our neighbors have lost their lives, and at least 17 others have been injured, including one firefighter.
My heart is with the families and loved ones mourning those we have lost. I am also wishing a full and speedy recovery to everyone who was injured.
This has been a whole-of-government response. I want to thank the first responders who arrived in under a minute and have spent hours working in dangerous and highly technical conditions to rescue New Yorkers. Their courage and dedication are extraordinary.
@nycemergencymgt and the @redcross have opened a reception center for impacted and displaced residents at the Flatbush YMCA, located at 1401 Flatbush Avenue.
If you are unable to reach someone you believe may have been affected by the collapse, please call 311. If you are outside New York City, call 212-639-9675.
Flatbush Avenue remains closed between Clarendon Road and Bedford Avenue. Please avoid the area so emergency crews can continue their work.
This remains an active operation, with hundreds of rescue workers on site. Information is changing by the minute. We will share additional updates as details are confirmed.

This Veterans Day, let us renew our commitment to those who served by confronting the injustices too many veterans still face, from homelessness and isolation to the threat of deportation.
Our responsibility to those who served does not end when they come home.
Progress isn’t inevitable. It’s fought for and earned.
New York City will now give community organizations the first shot at buying eligible homes — not flippers who are just looking to extract a profit.
This is the largest Opportunity to Purchase program in the nation.
Thank you @CMSandyNurse for your leadership on the COPA bill. Our city’s tenants are stronger because of it.

Winter is coming and our administration is prepared.
❄️ $25 million invested to keep New Yorkers safe on the coldest days.
 ❄️ 2,200 vehicles to build the nation's largest snow-clearing fleet.
 ❄️ 8 new plow routes on Staten Island.
 ❄️ Hundreds of workers ready to canvass our streets for vulnerable neighbors.
 ❄️ 55 vans staffed with medical professionals to help New Yorkers in need.
 ❄️ Dozens of new warming centers and warming buses.
 ❄️ 800 new beds for New Yorkers in need of a safe, warm place to sleep.
Companies like Amazon build business models around denying workers their rights and make our streets less safe.
It's time for that to change.
Let's pass the Delivery Protection Act.

Power has been restored to the affected areas of Brooklyn, and most traffic signals are operating normally. If you encounter a traffic signal that is still not working, use caution at the intersection and report it to 311.
We are coordinating with Con Edison and investigating a power disruption in Flatbush, Brooklyn, that may affect several thousand customers. There are also reports of traffic signals being disrupted in the area.
Use extra caution at intersections with nonworking traffic signals:
Drivers should treat nonworking traffic lights as stop signs. Come to a complete stop and yield before proceeding, unless directed otherwise by emergency personnel.
Pedestrians should use crosswalks, look in all directions, and wait until traffic has stopped before crossing. Do not assume drivers will stop.
Cyclists should slow down, be prepared to stop, and yield to pedestrians in crosswalks. Watch for vehicles approaching from all directions.
Drivers and cyclists must stop for pedestrians in marked and unmarked crosswalks when signals are not operating.
Report malfunctioning traffic signals to 311.
Call 911 for immediate life safety concerns.

We searched over 200 businesses for illegal e-bike and e-scooters — and issued 130 citations in 77 summonses for law breakers.
Putting New Yorkers at risk isn’t a profit model in our city.
