The NYPD has deployed its elite counterterrorism teams to busy areas of the city after multiple people were killed or injured in what British authorities described as terrorist attacks in London.
The department said that while there were no specific or credible threats to New York City, it had deployed its Critical Response Command to tourist hot spots and areas with heavy pedestrian traffic, such as Times Square.
An NYPD spokesman told NBC 4 New York that the department "is monitoring events in London and officials are in touch with their British counterparts."
Gov. Cuomo condemned the attacks in a statement and said he has directed state law enforcement officials to step up security patrols at high-profile locations in the state, including airports, bridges, tunnels and mass transit systems.
Mayor de Blasio tweeted Saturday that people in New York shouldn't be alarmed by the increased police presence.
In another tweet, the mayor said, "New York City stands with the people of London. Our prayers are with the victims, their families and the courageous first responders."
NYPD Commissioner James O'Neill tweeted that his department stands with police in London, and all first responders across the world who "bravely, professionally, and quickly handle cowardly attacks."
British police said they were dealing with two incidents related to terrorism near London Bridge and Borough Market on Saturday night, and that multiple casualties had been reported.
The attack at London Bridge involved firearms, a car and knives, police told NBC News. Meanwhile, shots were fired after police responded to reports of stabbings in Borough Market, police said.
Witnesses reported a vehicle hitting pedestrians and injured people on the ground at the London Bridge.
Prime Minister Theresa May said the attacks were being treated as a "potential act of terrorism."
President Trump began tweeting about the attacks an hour or so after initial news reports.
Trump renewed calls for his travel ban in one tweet, and expressed support for the British in another, writing: "Whatever the United States can do to help out in London and the U. K., we will be there - WE ARE WITH YOU. GOD BLESS!"
