Iran launched multiple deadly waves of missiles and drones toward Israel into Saturday morning following Israel’s unprecedented strikes aimed at destroying Iran’s nuclear program and decapitating its military leadership.

Iran says it has built and will activate a third nuclear enrichment facility, ratcheting up tensions with the U.N. immediately after its atomic watchdog censured Iran for failing to comply with obligations meant to prevent it from developing a nuclear weapon.

The two powers have been exchanging barrages since Israel attacked Iran and killed many of the country’s top military leaders and scientists.
