New York City is open for business, and don’t let the terrorists tell you any different. 
 
 That was the defiant message Wednesday night from Mayor de Blasio and Police Commissioner Bill Bratton, just hours after crazed jihadists released a threatening video that put a bullseye on the Big Apple.

 “I encourage all New Yorkers to remain alert and report any suspicious activity, while at the same time not letting this disrupt their daily lives,” Cuomo said in a statement. “Remember that the terrorists’ goal is to let fear win — New Yorkers never have, and we never will.” 
 
 The terrorist group released a video Wednesday promising more violence in the wake of last Friday’s Paris attacks that killed 129 people and injured hundreds more.

 New York City's mayor and police commissioner vowed the Big Apple would not live in fear of threats from the terror group ISIS, which on Wednesday released a video showing New York landmarks and referencing the Paris attacks. 
 
 "The people of New York City will not be intimidated," Mayor Bill de Blasio told reporters in Times Square Wednesday night. "We understand it is the goal of terrorists to intimidate and disrupt our democratic society. We will not submit to their wishes." 
 
 The terror group released a propaganda video Wednesday showing Times Square and other landmarks, and referencing the Paris terror attacks. 
 
 The images of New York City were published in April, and officials said the threats are not new. ISIS has claimed responsibility for Friday's terror attacks in Paris that killed 129 people. 
 
 New York City Police Commissioner William Bratton said the video appears to be "hastily produced, it is a mishmash of previously released video" that includes parts of other previously released videos that threatened Germany and Israel. 
 
 "There is, as we have repeated frequently, no city in America that is better prepared to defend and protect against a terrorist attack," Bratton said.

 The NYPD increased security after the Paris attacks out of an abundance of caution, including deploying heavily-armed police teams throughout the city. The FBI said it was aware of the video, but added there is no specific threat to the city. 
 
 In 2010, Faisal Shahzad tried to detonate a car bomb outside a theater in Times Square. The explosive failed to detonate. Shahzad said the Pakistani Taliban provided him with funding and training for attack. He pleaded guilty to federal charges and was sentenced to life in prison with no possibility of parole. ||||| (CNN) A video released by ISIS on Thursday threatens new attacks in France, Italy, the United States and beyond. 
 
 The video features two suspected ISIS fighters threatening to blow up the White House and launch more attacks on Paris. One fighter mentions a "conquest of Rome." 
 
 The Vatican's St. Peter's Square was recently featured on the cover of the terror group's online magazine. 
 
 Italy has responded to the video and magazine by beefing up security in Rome and the Vatican, with 1,000 members of the army being deployed around the country. 
 
 The U.S. Embassy in Rome is urging Americans visiting Italy to remain vigilant and aware of their surroundings amid the latest ISIS threats. It warns that St. Peter's Basilica in Rome, as well as Milan's Duomo and La Scala, could be terrorist targets. 
 
 The Embassy warns that "general" venues such as houses of worship, restaurants, theaters and hotels in Rome and Milan could be targeted. 
 
 Wednesday, the terror group released a video warning of an impending attack on New York City. 
 
 The video mentions Times Square and purports to show an explosive device being put together and a bomber zipping his jacket over a suicide belt. 
 
 The New York City Police Department said it was aware of the video and was deploying additional members of its new anti-terrorism squad out of an abundance of caution. 
 
 "While some of the video footage is not new, the video reaffirms the message that New York City remains a top terrorist target," the statement said. "While there is no current or specific threat to the city at this time, we will remain at a heightened state of vigilance and will continue to work with the FBI, the Joint Terrorism Task Force and the entire intelligence community to keep the city of New York safe." 
 
 Mayor Bill de Blasio encouraged New Yorkers to go about their normal business. 
 
 "The people of New York City will not be intimidated," he said late Wednesday. "We understand it is the goal of terrorists to intimidate and disrupt our democratic society. We will not submit to their wishes." 
 
 A similar video was released in April, according to John Miller, the NYPD deputy commissioner of intelligence and counterterrorism. 
 
 "This is an old video that was kind of rehashed," he said. "This is ISIS doing what ISIS and al Qaeda and terrorist groups do, which is propaganda." 
 
 "When we see the video, we make note of it, but it's like a lot of videos we've seen," Miller said. 
 
 CNN terrorism analyst Paul Cruickshank said authorities can't ignore the video, whether or not it turns out to be a credible threat. 
 
 "I think they have to treat it quite seriously, because ISIS is the richest terrorist group in history. It has an extraordinary number of Western recruits. ... One of its biggest ambitions right now is to a launch a terrorist attack inside the United States," he said. 
 
 ISIS first drew international attention for taking over swaths of Iraq and Syria, leaving a trail of violence and destruction in its wake. Its efforts to bring terror to the global stage seem to be growing. 
 
 Earlier this week, another video released by ISIS threatened to strike Washington.
– It will take more than an ISIS video to intimidate New York City, a defiant Mayor Bill de Blasio said Wednesday night after the group released a propaganda video mentioning the Paris attacks and threatening that New York City could be next. "The people of New York City will not be intimidated," de Blasio said in a Times Square press conference, per NBC. "We understand it is the goal of terrorists to intimidate and disrupt our democratic society. We will not submit to their wishes." CNN reports that the NYPD is deploying extra officers out of an "abundance of caution" following the release of the video, which shows footage of sites, including Times Square, and depicts a bomber with a suicide belt. De Blasio was joined in Times Square by NYPD Commissioner Bill Bratton, who said the "hastily produced" video shouldn't scare away visitors, the New York Daily News reports. "People can feel comfortable coming into the city," he said. "Do not be afraid. The NYPD will protect you." NY Gov. Andrew Cuomo also urged New Yorkers not to give terrorists the reaction they're hoping for, the Daily News reports. "I encourage all New Yorkers to remain alert and report any suspicious activity, while at the same time not letting this disrupt their daily lives," he said in a statement. "Remember that the terrorists' goal is to let fear win—New Yorkers never have, and we never will." (ISIS says it brought down a plane with a bomb in a soda can.)
