Russian President Vladimir Putin is warning the U.S. against using force on Iran, saying it would have catastrophic consequences.
Tensions have been building up recently over last week's attacks on tankers near the Strait of Hormuz, assaults that Washington has blamed on Iran. Iran has denied the accusations.
Speaking on Thursday during a televised call-in show, Putin said the U.S. military action against Iran would be a "catastrophe for the region as a minimum."
He added that it would trigger an escalation of hostilities with unpredictable results.
Putin noted that Iran has abided by the terms of a nuclear deal despite the U.S. withdrawal, adding that he considers U.S. sanctions against Iran unfounded.
