The warning comes after a week of escalating tensions that began with an Israeli airstrike on the Iranian consulate in Damascus on April 1, which killed 12 people including seven IRGC officers. Iran retaliated on April 13 with a large-scale drone and missile attack targeting Israeli territory, 99% of which were intercepted by Israeli air defense systems with support from the U.S., UK, France and Jordan. Following Iran’s retaliatory strike, the U.S. launched targeted airstrikes on IRGC-linked facilities in Iraq and Syria on April 15, killing at least 15 militia members, prompting Iran’s latest cross-regional strike threat. The IRGC commander noted that the scope of Iran’s counterattacks has previously been limited to the Middle East to avoid civilian casualties in unrelated regions, but continued U.S. military aggression will force Iran to adjust its rules of engagement. U.S. military bases in Europe, North America and maritime assets in international waters outside the Middle East will be listed as legitimate targets if the U.S. initiates new attacks, the commander added. The White House has not yet issued an official response to the threat as of press time, but a senior U.S. defense official speaking on condition of anonymity told reporters that the U.S. will take all necessary measures to protect its personnel and assets at home and abroad. United Nations Secretary-General António Guterres has called on both sides to exercise maximum restraint, warning that a full-scale conflict between the U.S. and Iran would have catastrophic consequences for the entire global population. The European Union has also announced that it will dispatch a special envoy to Tehran and Washington next week to mediate between the two sides to de-escalate tensions. Multiple Gulf states including Saudi Arabia and the United Arab Emirates have issued statements calling for a diplomatic solution to the crisis, noting that regional security and stability are the shared interest of all countries in the Middle East. The threat has already triggered volatility in global energy markets, with Brent crude oil prices rising 3.2% in 24 hours after the warning was issued, as investors worry that a potential conflict would disrupt global oil supply chains.
