Iran retaliated by launching waves of drones and ballistic missiles at Israel, where explosions lit the night skies over Jerusalem and Tel Aviv and shook the buildings below. The Israeli military urged civilians, already rattled by 20 months of war sparked by Hamas’ Oct. 7 attack, to head to shelter for hours.

Iranian state media report more explosions, with blasts heard in Tehran, as Israel says its air force is hitting military targets.

The Israeli military targeted Iranian nuclear facilities, research scientists and senior military commanders in dozens of preemptive airstrikes​.
