Hezbollah leader Hassan Nasrallah killed in Israeli airstrikes on Beirut

Hezbollah leader Hassan Nasrallah and other commanders were killed in Israeli airstrikes on Beirut, the group and Israeli officials confirmed on Saturday. After his death was confirmed, Israel continued firing strikes on the city.

Israel said it struck over 140 Hezbollah targets overnight and into Saturday morning.

Israel also hacked the control tower system at the Beirut Airport on Saturday to warn an Iranian passenger plane that was headed for Beirut not to land there, a senior official at the Lebanon Ministry of Transport confirms to ABC News. The Lebanese Minister of Transportation then told the plane not to enter Lebanese airspace.

Israel used bunker busters -- a munition designed to penetrate targets underground -- in the strike that killed Nasrallah, targeting a location underground embedded under a residential building in the area of Dahieh in Beirut, according to an Israel official familiar with the strike. Israel said the strike was conducted while the group's senior chain of command were operating from their headquarters.

"Hassan Nasrallah, the leader of the Hezbollah terrorist organization and one of its founders, was eliminated by the IDF, together with Ali Karki, the Commander of Hezbollah's Southern Front, and additional Hezbollah commanders," the IDF said in a statement issued on Saturday morning.

"During Hassan Nasrallah's 32-year reign as the Secretary-General of Hezbollah, he was responsible for the murder of many Israeli civilians and soldiers, and the planning and execution of thousands of terrorist activities," the IDF statement read. "He was responsible for directing and executing terrorist attacks around the world in which civilians of various nationalities were murdered. Nasrallah was the central decision-maker and the strategic leader of the organization."

The IDF said that they will continue to operate "against anyone who promotes and engages in terrorism against the State of Israel and its people."

Hezbollah called the killing of its leader and the targeting of residential buildings in Beirut "a cowardly terrorist act, a massacre and a heinous crime." The group vowed to "continue its jihad in confronting the enemy, supporting Gaza and Palestine, and defending Lebanon and its steadfast and honorable people.”

Despite the strike targeting Hezbollah leader Nasrallah on Friday and massive overnight strikes on Lebanon, Hezbollah continues to fire rockets and missiles into Israel. So far, releasing seven statements on attacks toward Israel on Saturday.

Tensions have continued to rise between Israel and Hezbollah in recent days with Israeli officials saying they are preparing for a ground invasion into Lebanon. Israel has targeted and killed several high level Hezbollah officials since it began its attacks on Lebanon.

In recent days Israel Prime Minister Benjamin Netanyahu said it will continue fighting against Hezbollah "with full force," warning Iran -- which backs Hezbollah -- and the entire Middle East.

"There is no place in Iran that the long arm of Israel cannot reach. And that is true of the entire Middle East," Netanyahu said, speaking to the United Nations General Assembly.

"If you strike us, we will strike you," Netanyahu said, addressing Iran.

The leader of Iran, Ayatollah Khamenei, released a statement that didn't comment on the death of Nasrallah, but insisted that "the resistance" will not be destroyed. The "fate of the region" will be decided by the "resistance forces and at the head of them is Hezbollah," he said in a statement.
