Israel launched airstrikes against Iran in retaliation for an earlier Iranian attack, raising fears of an all-out war between the two countries. Explosions were reported in Tehran, and Iranian state media said they occurred near or at Imam Khomeini international airport. The United States confirmed the attack but did not comment further. The recent exchanges between Israel and Iran have deviated from their usual practice of avoiding direct military clashes, and the conflict threatens to escalate into a global war.
