Canada's been attacked again by alleged Islamist militants in just barely two days. The seemingly lone wolf attack that locked down Canada's Parliament Hill on Wednesday morning is now being connected to the radical extremist ISIS. Since Canada officially declared war against the group when it joined the U.S.-led coalition early this month, the country had invited itself to become a target for the blood-hungry militants.

A report by Fox News, citing unidentified counterterrorism sources, said an increase in ISIS-related online chatter was observed five days prior to the Wednesday rampage in Ottawa. The chatter reportedly focused on Canada. The words "day of reckoning" was mentioned as chatters talked about Canada's decision to join the U.S.-led coalition against ISIS.

The lone gunman, identified as Michael Zehaf-Bibeau, stormed the Canadian Parliament. He shot a soldier and sprayed as many as 30 shots inside the government building. Epoch Times reported he got as far as the library before Kevin Vickers, parliamentary sergeant-at-arms, shot him dead. Zehaf-Bibeau is believed to be a Canadian national of Algerian descent, born in 1982.

Zehaf-Bibeau was described as "dressed in all black with a kerchief over his nose and mouth and something over his head as well, holding a rifle and shooting an honor guard in front of the cenotaph point-blank, twice," the Canadian Press news agency quoted a certain Tony Zobl.

BBC News gathered from a Canadian parliament official that the gunman looked "Arabian" with "long hair and a small beard."

It is believed Zehaf-Bibeau had been as a "high-risk traveler," prompting the government to confiscate his passport, Epoch Times said, citing the Globe and Mail. It was also discovered that Zehaf-Bibeau had been previously arrested five times for drug possession and for parole violations.

Although Canadian federal authorities have yet to confirm if Zehaf-Bibeau does have relations to the ISIS, an ISIS-affiliated Twitter account allegedly posted a picture of him.

On Sept 21, the ISIS released a video message that singled out Canada and three other nations. Translated in English, the message read: "If you can kill a disbelieving American or European - especially the spiteful and filthy French - or an Australian, or a Canadian, or any other disbeliever from the disbelievers waging war, including the citizens of the countries that entered into a coalition against the Islamic State, then rely upon Allah, and kill him in any manner or way however it may be."
