Tehran:Iranian officials have downplayed the recent US threats and vowed to respond if the security of Iranian territory was at stake.
US President Donald Trump had said on Wednesday that he has ordered the US Navy to shoot down and destroy Iranian gunboats if they harass their ships at the southern waters of Iran.
Before Trump's statement, the US Navy had earlier said in a statement that 11 military vessels of Iran's Islamic Revolution Guards Corps (IRGC) conducted "dangerous and provocative actions" near US Navy and Coast Guard ships in international waters in the Gulf on April 15.
Responding to Trump's threat, Hossein Salami, chief commander of the IRGC, on Thursday dismissed the claims, saying that the US' "unprofessional and hazardous" behaviour caused the IRGC Navy vessels' confrontation with American vessels last week.
Salami said: "We are fully determined and serious in defending our national security, maritime borders, maritime interests, maritime security and security of our forces at sea and any (wrong) move will trigger our decisive, effective and prompt response."
Also on Thursday, Iran's foreign minister Mohammad Javad Zarif said, "US forces have no business 7,000 miles away from home, provoking our sailors off our own Gulf shores".
