“Iran’s strategic policy is to reduce tensions, avoid any conflict and resolve regional crises through dialogue,” Shamkhani said on Wednesday.
“However, the country is fully prepared to monitor any intention or attempt to attack the Islamic Republic or its interests and will surprise aggressors most severely through a crushing and comprehensive response to possible evil actions,” he added.
The remarks came after Saudi Arabia said it would show evidence on Wednesday linking Tehran to an attack on its oil industry that Washington believes originated from Iran.
Iran denies any involvement.
The Yemeni forces on Saturday launched drone attacks on two plants at the heart of Saudi Arabia’s oil industry, including the world’s biggest petroleum processing facility.
The US has accused Iran of involvement in the attack, alleging that a number of cruise missiles have been fired from Iran at the Saudi targets. Iran vehemently denies the claim.
Since March 2015, Saudi Arabia and some of its Arab allies have been carrying out deadly airstrikes against the Houthi Ansarullah movement in an attempt to restore power to fugitive former president Abd Rabbuh Mansour Hadi, a close ally of Riyadh.
Official UN figures say that more than 15,000 people have been killed in Yemen since the Saudi-led bombing campaign began.
The Saudi war has impacted over seven million children in Yemen who now face a serious threat of famine, according to UNICEF figures. Over 6,000 children have either been killed or sustained serious injuries since 2015, UN children’s agency said. The humanitarian situation in the country has also been exacerbated by outbreaks of cholera, polio, and measles.
