Police in Ontario, Canada, killed a 23-year-old man Wednesday who had planned to carry out a suicide bombing in a nearby city, according to a report by CTV late Wednesday.

Police stormed the Strathroy, Ontario, residence of Aaron Driver after receiving a tip that the suspect was plotting an attack later that day. Witnesses of the raid reported hearing a loud explosion and gunshots as SWAT and bomb teams moved in on Driver.

"A suspect was identified and the proper course of action has been taken to ensure that there is no danger to the public's safety," a statement from the Royal Canadian Mounted Police said.

"The safety and security of Canadians is of the utmost importance to the RCMP and we take all such threats seriously. As this is still an unfolding matter and that the investigation is still underway, we are not able to provide further comment at this time."

Driver was well-known by federal agents and intelligence officials for sympathizing with the Islamic State in his social media posts. Officials did not state the Ontario city he had planned on targeting, but confirmed he prepared improvised explosive devices for an act that would see mass casualties.

Authorities believe Driver acted alone and said he was not instructed to carry out his plan by the Islamic State, but was a lone wolf motivated by the terrorist group. Driver is one of the first in Canada to have been targeted for attempting to support the Islamic State.
