The United States has designated Iran's Revolutionary Guards as a "foreign terrorist organization," President Donald Trump announced in an official statement on Monday.
It is the first time that the U.S. formally blacklists another country’s military as a terrorist group.
"This action sends a clear message to Tehran that its support for terrorism has serious consequences. We will continue to increase financial pressure and raise the costs on the Iranian regime for its support of terrorist activity until it abandons its malign and outlaw behavior," Trump said in a statement released by the White House.
"This is an unprecedented step that recognizes the reality that Iran is not only a State Sponsor of Terrorism, but that the IRGC actively participates in, finances, and promotes terrorism as a tool of statecraft," he added.
"The IRGC is the Iranian government's primary means of directing and implementing its global terrorist campaign," Trump stressed.
Iran's Supreme National Security Council slammed the designation as "illegal and dangerous", announcing it has reciprocated by labeling the U.S. as state sponsor of terrorism and by blacklisting the U.S Central Command (CENTCOM), and all related forces, as terrorist groups.
