Canada sanctioned six individuals and four businesses it said were among the worst offenders who participated in or aided “gross human rights crimes” in Iran.

“Canada will continue to support them by using all tools at our disposal to respond to the Iranian regime’s violations of human rights and its threats to regional peace and security,” Canada’s Foreign Minister Melanie Joly said in a statement.

The sanctions list includes Mohammad Karami of the Islamic Revolutionary Guard Corps Quds Force, a hardline watchdog body called the Guardian Council and the Assembly of Experts, which responsible for selecting Supreme Leader Ayatollah Ali Khamenei’s successor.
