Less than two weeks after the deadly terror attacks in Paris, New York City is on high alert as many fear that the Islamic State group may want to hit the Big Apple.

Both NYPD Commissioner William Bratton and New York City Mayor Bill de Blasio say that any potential threats from ISIS will not impact holiday shopping or the Thanksgiving Day Parade.

Last Sunday, the NYPD held an active shooter drill, which was attended by Bratton and U.S. Secretary of Homeland Security Jeh Johnson.

De Blasio appeared on "Good Day New York" Wednesday morning, saying the city is ready for the parade.

"This parade, we've been doing for years, it's one of the biggest events in the country all year. And you saw what the NYPD did with the pope's visit and the U.N. General Assembly and so many other big moments, the preparation is outstanding. But now we've even added more capacity," de Blasio says.

That extra capacity is coming in large part from the the new Critical Response Command introduced last week. Randall's Island is home to the unit comprised of 500 new counterterrorism officers.

President Barack Obama also assuaged fears on Wednesday, saying that there is no credible intelligence about a plot against the U.S. He encourages citizens to carry out their holiday festivities as planned.

More than 10,000 people are expected to be taking part in the Thanksgiving Day Parade.
