WASHINGTON (Sputnik) — There is currently no information to suggest Driver had any other accomplices, Cabana noted.
"Based on the information, the attack was supposed to be taking place within the following 72 hours and was likely to target an urban center, either during morning or afternoon rush hour," Cabana told reporters.
Cabana explained that the US Federal Bureau of Investigation (FBI) alerted the RCMP to the pending attack and turned over a "martyrdom" video that Driver filmed of himself.
Driver stated that he targeted Canada because of its membership in the US-led coalition against Daesh.
The 24-year-old was already under investigation for social media posts sympathetic to the Islamic State, Cabana noted. Additionally, he had been in contact with UK-born IS operative Junaid Hussain, as well as Elton Simpson, who attempted to attack a cartoon contest in Texas in 2015.
Driver was killed on Wednesday when officers tried to apprehend him at his home in Ontario. RCMP Assistant Commissioner Jennifer Strachan said investigators will determine if he was killed by police or by shrapnel from a homemade explosive device that he detonated during the incident.
