MNA � IRGC is in charge of providing the Persian Gulf with security and after US decision to blacklist the force, new incidents may happen in the region, warned Iran�s Deputy Foreign Minister Abbas Araghchi.

He made the remarks late on Monday in an interview with IRIB after the Trump administration�s hostile decision to designate the Islamic Revolutionary Guards Corps as a terrorist organization.

�The US recent measure is a political and strategic mistake,� highlighted Araghchi, adding that Washington has crossed one of the fundamental redlines of the Islamic Republic.

US decision leads to a �very serious� change in Iran-US interactions and Tehran will give a �firm and clear� response, he noted.

Forces of US Central Command (CENTCOM) play a direct and indirect role in all crimes that have happened in Syria, Yemen, and Palestine, he said, adding that from now on, Iranian forces� behavior towards Americans will change.

�From now on, American forces in their military bases in the region are not soldiers; from our view, these are terrorist bases and the forces deployed there are terrorists.�

Iran's Supreme National Security Council (SNSC) decided to designate the US Central Command-the CENTCOM-and the related forces as a terrorist organization in retaliation to US similar action against the IRGC.
