Hezbollah leader Hassan Nasrallah was killed in an Israeli airstrike on Friday.
Israel is firing strikes into Lebanon as the conflict in the Middle East intensifies.
Israel believes it has eliminated around 30 top Hezbollah leaders over the last several weeks, including Hezbollah leader Hassan Nasrallah, who was killed in an Israeli airstrike in Beirut on Friday, U.S. and Israeli officials said.
The Israel Defense Forces said Wednesday it was again "conducting extensive strikes in southern Lebanon and the Bekaa area" to the east of Beirut.
Almost 600 people -- including at least 50 children -- have been killed by Israeli strikes across Lebanon since Monday, according to the Lebanese Ministry of Public Health.

Hezbollah claimed the launch of a Qadir-1 ballistic missile targeting the Mossad intelligence agency's headquarters on the outskirts of Tel Aviv on Wednesday morning.
"It is the headquarters responsible for the assassination of leaders and the bombing of pagers and hand-held radios," the militant group said in a statement, referring to last week's communication device explosions in Lebanon and Syria.
Sirens sounded in Tel Aviv amid the attack. "One surface-to-surface missile was identified crossing from Lebanon and was intercepted," the Israel Defense Forces said in a statement.
The IDF later said in a social media post that it destroyed the launcher from which the missile was fired in southern Lebanon.
The launch at Tel Aviv is the first time Hezbollah has attacked the city in central Israel since the war in the Gaza Strip began on Oct. 7.
