Iran has issued a sharp warning after U.S.-Israeli strikes destroyed a key bridge near Karaj, raising fears of a wider regional escalation. Iranian state media has listed major bridges across the Gulf and Levant as potential targets in a “tit-for-tat” response, signaling a shift toward critical infrastructure warfare. From Saudi Arabia to the UAE and Jordan, strategic links are now in focus. Tehran has condemned the strike as an attack on civilian infrastructure, while also vowing continued retaliation. As tensions rise, the conflict is rapidly expanding beyond traditional battlefields.
