Iran fired hundreds of drones and ballistic missiles at Israel in two attacks last year in response to Israeli strikes, rattling the Israeli public but causing only modest damage. Tehran has vowed retaliation for Israel's early morning attack on Friday on Iranian military and nuclear facilities that killed several top commanders.

Iran has vowed that Israel and the U.S. will pay a “heavy price,” according to a military spokesperson, after Israel launched “preemptive” strikes early Friday local time on Iran, amid growing regional tensions and concerns about Iran’s nuclear capabilities.
