In the wake of the deadly terrorist attacks in London, Homeland Security said Sunday there’s no evidence of “a specific, credible terror threat in the United States.”
Still, the federal agency is remaining vigilant and monitoring the situation, the USA Today reports. 
New York Mayor Bill de Blasio said the city was on high alert, and critical response units have been placed in “particularly prominent” locations throughout the city.
“That means New Yorkers today will see a heavier presence at key locations around the city,” he said Sunday while speaking to reporters. “You will see a stronger police presence, including our counter-terror forces, which are heavily armed and heavily geared.”
Still, he said, this “is not a cause for alarm – that is a cause for comfort, to see the NYPD out in strength to protect u against any situation,” the mayor said.
So far this year, there have been 500 terror attacks that lead to 3,500 deaths “and many more physically and mentally wounded” said Tom Cochran, CEO and executive director of the U.S. Conference of Mayors.
Homeland Security has cautioned U.S. citizens in London to “maintain security awareness.”
