Ottawa battens down for Canada Day as ISIS threatens attack

While heavy rain is expected to dampen Canada’s 150th birthday celebrations Saturday on Parliament Hill, high-level security experts in both police and intelligence agencies are hoping the only explosions heard will be emanating from the thunder clouds overhead.

A national security memo, obtained by CTV News, has the ISIS terror group again “explicitly” naming Canada as a target, with its text warning Muslims to avoid markets and large gatherings as it threatens to use “explosives, vehicles and beheadings to kill crusaders.”
