American authorities say a 19-year-old Canadian has pleaded guilty to terrorism-related charges in connection with what they call an ISIS-inspired plot to target landmarks in New York City – including Times Square and the subway system.

The Canadian is identified as Abdulrahman El Bahnasawy, of Mississauga.

He’s been in custody since the FBI arrested him in New Jersey in May 2016.

The arrest was first announced Friday – after a court’s unsealing of federal terrorism charges against three men.

The other two accused are identified as Talha Haroon, a 19-year-old U.S. citizen residing in Pakistan – and Russell Salic, 37, from the Philippines.

U.S. authorities allege that the three communicated through Internet messaging applications – allegedly plotting to carry out bombings and shootings in heavily populated areas of New York City – during the Islamic holy month of Ramadhan in 2016.

It’s also alleged that while in Canada – El Bahnasawy purchased bomb-making materials and helped secure a cabin within driving distance of New York City – to use for building the explosive devices and staging the attacks.

The RCMP has issued a statement saying it collaborated with the FBI in the investigation – that led to El Bahnasawy’s arrest.

He’s scheduled to be sentenced on December 12th this year.
