The gunfight inside Canada’s Parliament building came just a day after the country heightened its terrorism warning in response to a murderous attack on two soldiers by a radical Muslim convert.

On Monday, self-proclaimed ISIS supporter Martin Couture-Rouleau fatally mowed down Warrant Officer Patrice Vincent and injured another soldier in an intentional hit-and-run outside a military recruiting office in Quebec.

He was shot dead by cops after he flipped his Nissan Altima during a botched getaway and crawled out of the wreckage while brandishing a large knife.

Canadian Public Safety Minister Steven Blaney said Couture-Rouleau’s rampage was “clearly linked to terrorist ideology,” and officials in the Great White North raised their terror alert level from “low” to “medium.”

Late last month, ISIS spokesman Abu Mohammed al-Adnani urged the terror group’s followers to kill “disbelieving” civilians in the US and elsewhere — including Canada — “in any manner or way.”

“Smash his head with a rock, or slaughter him with a knife, or run him over with your car, or throw him down from a high place, or choke him or poison him,” al-Adnani ranted in a speech spread via Twitter.

Couture-Rouleau, 25, converted to Islam last year and dubbed himself “Abu Ibrahim AlCanadi” on a Twitter page that features ISIS’s black-and-white banner as his profile picture, according to reports.

Neighbors also said he grew a bushy beard and started wearing a tunic.

“He used to be a good guy, very normal, a father,” former friend Jonathan Lachapelle told The Globe and Mail newspaper. “But he started to change. He spent a lot of time on the Internet and got brainwashed.”
