NYPD Commissioner James O'Neill says the police department has "strategically placed resources" around the city in response to an attack near the Parliament building in London Wednesday.
Police say a man used a car to plow into pedestrians on the city's Westminster Bridge. They say he then fatally stabbed a police officer outside of Parliament. He was shot and killed by police shortly after.
Five people were killed. At least 40 other people were injured.
In response, the NYPD has dispatched teams of officers to protect sensitive areas around New York City.

The Parliament building was placed on lockdown following the attack.
Officials in London say they have launched a terrorism investigation.
The NYPD says it has deployed additional counterterrorism resources across the city out of an abundance of caution.
They say there no threats to the city at this time.
The White House says President Donald Trump has been briefed on the incident.
The Department of Homeland Security also released a statement saying they are in contact with British authorities, adding "At this time our domestic security posture remains unchanged. However, our frontline officers and agents continue to stay vigilant in safeguarding the American people and our homeland."
