A week after calling for violence on Election Day, a terrorist group has now put out the word to perhaps attack people celebrating a major American holiday. NY1's Dean Meminger filed the following report.

Millions of spectators usually come out to enjoy the Macy's Thanksgiving parade, and the NYPD says it's keeping a close watch to make sure the event is not attacked by terrorists. Especially since the Islamic State group has indicated the parade would be a good target for someone to perhaps drive a truck into. 

"Carry out vehicle-borne assaults across the world and on different targets," said John Miller, NYPD deputy commissioner of intelligence and counterterrorism. "One issue of concern is a photograph that was contained in the article of the Thanksgiving Day Parade."

The article appeared in the terror group's online magazine Ramiyah this past weekend. 

Using a picture of the parade brings back memories from this past July on Bastille Day in France. Someone drove a truck into the crowd at the national celebration killing 86 people. So you can expect to see NYPD cars and even city sanitation trucks protecting the Thanksgiving parade route. 

"This is not something that occurred to us over the weekend when we saw the article in ISIL's online magazine," Miller said. "This is an element we've factored into plans for the Thanksgiving Day parade in years past."

And the NYPD's incident prevention unit is in contact with truck rental companies in the tri-state area encouraging them to be on the lookout.

"Provided them with very useful guidance on how to identify suspicious behavior and characteristics amount people who are potential renters of their vehicles."

The NYPD says it's not clear if the presidential election has anything to do with the article calling for attacks around the world.

"I think if you are looking at this through the optic of al-Qaida or ISIL, I don't think they like either candidate, or America in particular, or democracy," Miller said.

Police admit that all it takes is one person to heed the call of violence to cause serious harm, but they say they are using all their resources to try to prevent that from happening. 

"Come to the thanksgiving day parade. Have a good time. Bring the family," Miller said. 

Macy's responded to the possible threat in a statement.

The statement reads, "Macy's works closely with the NYPD and federal law enforcement agencies each year to put in place comprehensive security plans for the Macy's Thanksgiving Day Parade. Our interagency partners lead security efforts along all areas of the Parade route and we are in constant communication with these agencies as they actively monitor and evaluate parade security. As with any public event in New York City, security elements are extensive from the very visible presence of law enforcement officers to wide-ranging behind-the-scenes security operations. The safety of our participants and spectators is the top priority for us and our agency partners. We look forward to putting on a great Parade for millions of New Yorkers and fans from around the world."
