Israel’s air defenses—a multilayered system that includes the famed Iron Dome—are among the best in the world and the most battle-tested, but even so they aren't completely impenetrable, Israeli officials and air-defense experts say.

A rare daytime missile barrage on Tel Aviv forces millions into shelters as Israeli forces retaliate against Iran's missile-launching capabilities.

Iran fired a new wave of missile attacks at Israel, killing at least eight people, while Israel warned hundreds of thousands of people in the middle of Tehran to evacuate ahead of new strikes

Israeli authorities have signaled that the barrage appears to have subsided, giving the all clear for people to leave their shelters. They said that emergency services were responding to reports of damage from the missiles and are providing treatment to several people with minor injuries.

Iran's nuclear program will be hard to dismantle, but Israel has increased its superiority in missile and air defence capabilities
