Iran launched the largest missile attack on Israel to date on Tuesday, with hundreds of missiles fired into the country, according to Danny Danon, Israel's ambassador to the United Nations.

Iran said the unprecedented attack was retaliation for a wave of assassinations carried out by Israel over the last several weeks targeting Hezbollah, including leader Hassan Nasrallah.

Sirens sounded across Israel and some citizens were urged to seek shelter in protected areas. Most of the missiles were intercepted, but "several hits were identified, and the damage is being assessed," an Israeli security official said.

The U.S. fired missiles to help Israel defend itself against the missile attack, according to the Pentagon's Maj. Gen. Pat Ryder.

DHS warns of potential cyberattack threat against US following killing of Nasrallah

The Iranian regime is unlikely to take direct military action against the U.S. homeland following Israel's killing of Hezbollah leader Hassan Nasrallah, though his death could prompt Iran or its proxies to take alternative actions like cyberattacks, according to a new Department of Homeland Security alert.

Nasrallah's death is also unlikely to galvanize people within the U.S to take action, though the "expansion of the regional conflict and potential for increased circulation of graphic images highlighting civilian deaths could contribute to [extremist] radicalization to violence,” according to the Sept. 30 document obtained by ABC News and distributed to law enforcement agencies around the country.

"We also assess that it is unlikely that Iran or its proxies will target the homeland during any potential physical response to the airstrike,” the alert stated. "We are concerned that the incident may prompt Iranian government or other malicious cyber actors supportive of Tehran's interests to conduct cyber attacks against poorly secured US critical infrastructure entities, among other targets."
