A counterterrorism source tells Fox News that there was a spike in Islamic State-related online chatter focusing on Canada in the days leading up to the shooting Wednesday in the capital of Ottawa.
Multiple gunmen stormed the Canadian Parliament complex on Wednesday, shooting at least one soldier and spraying as many as 30 shots inside the government building. No one has yet claimed responsibility for the shooting.
But the counterterrorism source said there was an increase in chatter in the five days leading up to the attack, focusing on Canada's decision to join the U.S.-led coalition against ISIS -- including threats that the "day of reckoning" is coming.
ISIS followers also have taken to Twitter to comment on the Canada shooting.
One translated tweet provided to Fox News said: "soldiers of #Islamic_state who are everywhere around the globe declared war on the coalition countries"
