Back on July 25, US Secretary of State John Kerry said that US President Barack Obama "has made it pretty clear that Iran will not get a nuclear weapon. He's prepared to use military force, if necessary, in order to prevent that."
Speaking to a large congregation of worshippers in Tehran, Ayatollah Khatami referred to the remarks as “worn-out", adding that the US officials have repeatedly made similar threats since the victory of the Islamic Revolution in 1979.
“We would not welcome any war, but if Americans want to try their chance once again, they should not hesitate," he said, adding, "They may bring their warriors with aircrafts, but they would return to their cities with coffins."
“Even in ground offensive," the Iranian cleric added "they (enemies) should know that the Islamic Republic of Iran would chase enemies deep into the enemy’s territory."
Earlier in May, Supreme Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei reaffirmed that the Iranian nation will not let any possible act of aggression against the country go unanswered.
The Leader said he has already made it clear, even in the tenure of former US president, that "the era of hit and run has ended", and that the Iranian nation will chase aggressors.
