Israel-Gaza-Lebanon updates: Nasrallah killed for tying Hezbollah cause to Gaza war

Israel claimed it killed a top Hezbollah commander in Tuesday's strike on Beirut, which killed at least six people and injured 15 others, according to the Lebanese Ministry of Public Health.

The IDF said it targeted and killed Ibrahim Muhammad Kabisi, a commander of Hezbollah's missile and rocket array.

"Kabisi commanded the various missile units of Hezbollah, including the precision missile units. Over the years and during the war, he was responsible for the launches towards the Israeli home front. Kabisi was a central center of knowledge in the field of missiles and was close to the senior military leadership of Hezbollah," the IDF said in a statement.

The IDF also claimed he was responsible for the planning and execution of many terrorist plots against IDF forces and Israeli citizens.

At least six people were killed and 15 others were wounded after Israel carried out a strike on the Ghobeiry neighborhood of Beirut on Tuesday, according to the Lebanese Ministry of Public Health.

It appears the top floor of a concrete apartment building took the brunt of the strike.

The U.S. is continuing to urge Israel to avoid an "all-out war" with Lebanon as tensions between the two countries remain high, National Security Council spokesperson John Kirby said in an interview on "Good Morning America" Tuesday.

"I think we don't believe it's in Israel's interest for this to escalate, for there to be an all-out war there on the north on that blue line between Israel and Lebanon. If the goal is to get families back to their homes, we think there's a better way to do that than an all-out conflict," Kirby said.

"The Israelis will tell you, yesterday, that they had to take some of these strikes because they were about to be imminently attacked by Hezbollah. They do have a right to defend themselves, but what we're going to keep doing is talking to them about trying to find a diplomatic solution here, a way to de-escalate the tensions so that the families can go back in a sustainable way," Kirby added.

Given the State Department's warning to Americans to get out of Lebanon while commercial travel is still available on if he believes Israel may target airports in Lebanon as they have in the past.

"We want to make sure that there are still commercial options available for Americans to leave, and they should be leaving now while those options are available. But I won't get ahead of operations," Kirby said.

Kirby also dodged questions on what we might see from Hezbollah's response to Israel, telling GMA he "won't get into the intelligence assessment."

"It's obviously going to be something we'll monitor very, very closely. I will just tell you that while we won't get involved in the conflict itself there, around that blue line, because we don't want to see a conflict at all. We'll do what we have to continue to do to make sure Israel can defend itself."

At least 558 people have been killed -- including 50 children and 95 women -- and another 1,853 people wounded by Israeli strikes in Lebanon since Monday, according to the latest data from the Lebanese Ministry of Public Health.

Officials released the updated figures during a press conference on Tuesday.

The Israel Defense Forces said it struck at least 1,600 targets in Lebanon over the past 24 hours.
