"As we struck France in the center of its abode in Paris," they say. "Then we swear that we will strike America at its center in Washington."

INSIDE EDITION spoke to former New York Police commissioner Bernie Kerik in Times Square, who said: “We have to remain vigilant.”

“ISIS, whether it's through Facebook or social media, of course it's credible, and anyone who thinks it's not, look at Paris. They're going to do this. They're dead set on it. They tell us on a daily basis they're coming. If you don't know they're coming by now, you're a moron.”

Football fans experienced stepped up security at games across the nation.

The NFL is taking no chances after one of the targets in Paris was a soccer stadium. Fans were instructed to carry only see-through plastic bags, which were thoroughly screened.

Security at our nation’s airports has been stepped up too.

Traveler Seth Porges just arrived back in New York from Paris. The freelance journalist was staying in an Airbnb apartment near the restaurant that was attacked and saw the carnage first hand.

“I was checked or interviewed four or five times from when I stepped of the plane until I left the airport,” he said. “I see officers with guns out, crouched behind vans, people standing on benches, taking photos.”

As the nation stands in solidarity with Paris, thoughts are turning to ways of preventing similar carnage on our shores.

Bernie Kerik says we can all play a part in keeping this county safe, particularly with the Thanksgiving Day parade just two weeks away.

He said people should be on the lookout for “People in the wrong place at the wrong time, packages. Look at your surroundings. If you see something, say something.”

France is set to host one of the largest soccer tornaments in June with Euro 2016. Fans who want to attend the competition got a guarantee from Jacques Lambert, the president of the organizing committee that security will prevail above everything.

The month long tournament will take place in 10 cities across the country with the final being held in Paris at the Stade de France, were a bombing took place outside the stadium.

While security and safety is on the mind's of everyone, Anonymous has declared war on ISIS in a chilling new video posted online.

The hacker group said: “You should know that we will find you and we will not let you go… We will launch the biggest operation ever against you.”

"We are united against this threat," he said of the G20 members. "ISIL is the face of evil. Our goal is to degrade and ultimately destroy this organization."

Airstrikes against ISIS have intensified, he said, adding: "Both in Iraq and Syria, ISIL controls less territory than it did before."
