TEHRAN, Young Journalists Club(YJC)_Iran's top diplomat made the remarks in an exclusive interview with the CNN in Tehran on Thursday.
Asked what the consequence of a US or Saudi military strike on Iran would be, Zarif said: "All-out war."
"I make a very serious statement about defending our country. I am making a very serious statement that we don't want to engage in a military confrontation," Zarif said, adding that a military response based on "deception" about the weekend attacks on Saudi oil installations would cause "a lot of casualties."
"…We won't blink to defend our territory," Iran's foreign minister emphasized.
Tensions started to rise between Iran and Saudi Arabia after a group of Yemeni drones hit two oil facilities of Saudi Arabia's state oil giant Aramco in the country's east, causing huge fires before dawn on Saturday.
A spokesman for Saudi Arabia's Interior Ministry said in a statement that the attacks targeted two Aramco factories in Abqaiq and Khurais, without specifying the source of the attacks. However, Yemen's Houthi movement later claimed responsibility in an announcement on Al Masirah TV. The movement's military spokesman, General Yahya Sare'e, said 10 drones were deployed against the sites in Abqaiq and Khurais, and pledged to widen the range of attacks on Saudi Arabia.
