"One need not be a military expert or a martial arts master, or even own a gun or rifle, in order to carry out a massacre or to kill and injure several disbelievers and terrorize an entire nation," the group reportedly wrote, according to the New York Post.
The group encouraged followers to use the same truck-ramming tactics that were used in the Bastille Day attack in Nice, France, which killed 86 people and injured over 400.

"I definitely would have been notified [if such a threat existed]," a federal official said.
Manhattan's Thanksgiving Day parade is an annual event watched by millions, both on the street and on television, hosted by the US-based department store chain Macy's, beginning in 1924. The November 24 parade starts at Central Park West, lasts for three hours and covers a distance of about 2.5 miles through the city's streets.
