More than 50 Israeli jets flew over Tehran overnight, targeting nuclear and missile sites. Defense officials say their aim is to undermine Iran's leadership as U.S. involvement looms and regional tensions grow.

Iran launched three retaliatory waves of missiles at targets in Israel on June 13, as Israelis rode out the attacks in bomb shelters and world leaders discussed the deepening conflict. Plumes of smoke rose over central Tel Aviv and at least one building was hit and set ablaze.
