Over 1,000 people in Lebanon have been killed in the last two weeks.
Israel's Lebanon operation continues as leaders consider their response to Iran's long-range attack on Tuesday, in which hundreds of missiles were 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.
Most of the missiles were intercepted, but "several hits were identified, and the damage is being assessed," an Israeli security official said.

The Islamic Revolutionary Guard Corps said it targeted three Israeli military bases around Tel Aviv in its attack on Israel.
The Iranian Mission to the United Nations told ABC News that "no notice was given to the U.S. prior" to the attack, though a "serious warning was issued afterward."

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."
