Storyline: Iranian air defense systems were activated Thursday in response to "hostile targets" over the capital Tehran, Iran's state news agency IRNA reported. According to separate reports by state broadcaster Islamic Republic of Iran Broadcasting, the country's air defense systems downed Israeli drones in the south of Tehran. A substantial explosion took place early Friday morning in the northwestern Iranian city Rasht, prompting the activation of the local air defense system. According to reports, a local industrial park was the intended target of the attack. Israel and Iran exchanged airstrikes on Thursday night and Friday morning, targeting each other's critical infrastructures and military facilities. The Israel Defense Forces (IDF) announced in a statement on Thursday that it had launched a broad aerial campaign across Iran, including a strike targeting the inactive Arak nuclear reactor in western Iran. The IDF said the operation involved over 100 munitions, 40 fighter jets and intelligence coordination, targeting dozens of military sites throughout Iran, including its capital Tehran. In response to the Israeli offensive, Iran targeted Israel's military intelligence facilities in its strikes on the southern part of the country on Thursday morning, not a hospital as was reported by some media outlets, IRNA said. The rapid escalation marks the most direct, large-scale confrontation between the two regional adversaries in recent years. Shotlist: Tehran, Iran - June 19, 2025: 1.
