Three ISIL terrorists are facing charges over alleged plans to stage multiple attacks in New York City.
The three mostly communicated through messaging applications. Around May 6, he told the agent he had researched concerts in the New York City area looking for one in a "closed area" and "far away from cops".
USA agents stopped three sympathizers of the Islamic State militant group (ISIS) carrying out coordinated attacks on NY concert venues, subway stations and Times Square during the Islamic holy month of Ramadan in 2016.
Ahmad Khan Rahami was taken into custody for his alleged involvement in a bombing in Chelsea past year.
Abdulrahman El Bahnasawy also wanted to "bombard [a crowd] during concerts" to kill as many people as possible.
According to the court documents, El Bahnasawy and Haroon claimed to the undercover agent to have contacts with an ISIS branch known as Khorasan Province, which is active in Pakistan and Afghanistan. One of the suspects told an undercover Federal Bureau of Investigation agent he wished to "create the next 9/11".
NEW YORK-Three people, including Filipino jihadist Russel Salic, have been charged with involvement in a planned attack in New York City in 2016 during the Muslim holy fasting month of Ramadan, authorities here said.
"We need a really strong bomb", El Bahnasawy was quoted as saying, according to court documents.
Times Square saw a failed auto bomb attempt by terrorist Faisal Shahzad and the 2009 Zazi plot was set to be a series of backpack bombings on the subways.
"The US can also request for a temporary surrender of Salic to its custody, but it's in our options to require him to face criminal complaints here first", Paras said.
One of those attacks allegedly included planting a vehicle bomb in Times Square. That's how the Paris guys did it, ' the message said in apparent reference to the November 2015 attacks on the Bataclan theater, which left 130 dead in Paris.
In the course of their communication, they allegedly declared their allegiance to ISIS and expressed their intent to carry out attacks resembling the recent Paris and Brussels attacks.
Haroon identified Times Square as "a ideal spot to hit them" and expressed desire to "kill...them in thousands" and "leave no one standing". "No mercy is rule one", he wrote to the agent.
The two other men were arrested outside of the US and the hope, according to the release, is that they will be extradited to the USA for prosecution. The third defendant, 37-year-old Russel Salic of Pakistan, is accused of wiring money to fund the operation.Mr el Bahnasawy plead guilty to a seven-count charge last October.
