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 Israeli military does not see any additional threats at this time from Iran, Israel Defense Forces spokesperson Rear Adm. Daniel Hagari said.
Hagari said they have carried out a "large number of interceptions." There were a "few hits" in the south and officials are assessing the damage, though there are no reported casualties, he added.
"We are on high alert both defensively and offensively," he said. "We will defend the citizens of the State of Israel. This attack will have consequences."
The U.S. was involved in the effort to intercept some of the Iranian missiles launched against Israel, an official told ABC News.
"In accordance with our ironclad commitment to Israel’s security, U.S. forces in the region are currently defending against Iranian-launched missiles targeting Israel," the official said. "Our forces remain postured to provide additional defensive support and to protect U.S. forces operating in the region."

President Joe Biden said Tuesday the U.S. is prepared to help Israel defend against the Iranian missile attack.
Biden and Vice President Kamala Harris are monitoring the Iranian attack from the White House Situation Room and receiving regular updates from their national security team. Biden directed the U.S. military to aid Israel's defense against Iranian attacks and shoot down missiles.
Before the attack began, he posted on X that he and Vice President Kamala Harris had convened their national security team.
He said as well that the U.S. was ready to protect American personnel in the region.
