Following in the footsteps of the United States and Britain, Canada has frozen the assets of five Iranian nationals accused by Washington of plotting to kill Saudi Ambassador to US Adel Al-Jubeir, officials said Tuesday. “In response to credible allegations of the Iranian regime's involvement in an assassination plot last week, Canada is imposing new sanctions on five Iranian nationals believed to be complicit in its planning,” Foreign Minister John Baird said in a statement. The measures place travel restrictions on the five and ban any Canadian individual or entity from having financial dealings with them.
