An Iranian government official issued a chilling warning that his country is now able to launch a nuclear test in as little as one week.

       His statement on Monday came just hours after the Israeli foreign ministry spoke out against Iran's use of nuclear weapons as tensions continue to mount between the two countries.

       Karimi-Ghodousi has previously spoken out about the use of Iranian nuclear weapons as missiles, warning of retaliation should anyone strike his country.

       However, also on Monday, Iranian foreign ministry spokesperson Nasser Nanaani claimed "nuclear weapons have no place in our nuclear doctrine."

       During a press briefing in Tehran, he reiterated that Iran's nuclear program is "strictly for peaceful purposes".

       Islamic Revolutionary Guard general Ahmad Haghtalab recently said that Iran could forced to "review its nuclear doctrine and deviate from its previous considerations" in the wake of fresh threats from Israel.

       On Friday, Iran sustained damage to an airbase in Isfahan, with the attack reportedly damaging a major defence system near a nuclear facility.

       Nanaani called the attack, attributed to Israel, a "provocative act", warning that Iran "will respond decisively and more strongly to any aggressive action from any source."
