FBI Director Kash Patel says the flow of fentanyl drugs entering the US is now also coming from Canada.

Patel told Fox News that hostile regimes such as China, Russia and Iran are collaborating with cartels to smuggle the drug into the United States through Vancouver and the northern US border. This comes after US President Donald Trump's efforts led to the closure of the border with Mexico, in the southern US.

Patel called on Canadian authorities to take action and work harder to stop the flow of drugs.
