The US, alongside Israel, targeted the Karaj B1 bridge in Alborz Province, Iran, during a military operation aimed at disrupting logistics for the Islamic Revolutionary Guard Corps (IRGC). This bridge, recognized as the tallest in the Middle East, was under construction and serves as a vital transport link between Tehran and Karaj. The attack resulted in at least 8 deaths and nearly 100 injuries, primarily among civilians celebrating Nature Day. The US justified the strike by claiming the bridge was used to transport missiles and drone components, marking a shift towards targeting civilian infrastructure to weaken Iran's military capabilities. The destruction of the bridge has provoked a strong response from Iran, which has vowed to rebuild it and has identified other major bridges as potential targets for retaliation. This escalation reflects the ongoing tensions in the region, with both sides preparing for further confrontations.
