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 it carried out an operation against more Hezbollah targets early Monday morning local time.
The Israeli Air Force attacked targets in the Bekaa region of Lebanon, the IDF said in a statement.
Targets included launchers and buildings where the IDF said weapons were held.
The Israeli Air Force also attacked what it said were military buildings in southern Lebanon.

The death toll in Lebanon as a result of Israeli airstrikes Sunday rose to 105, according to the Lebanese Ministry of Health.
Nearly 360 individuals were wounded in the strikes, the ministry reported.
The strikes occurred in southern Lebanon, the Bekaa, Baalbek-Hermel and the southern suburbs of Beirut (Dahieh), according to the ministry.
Israeli Prime Minister Benjamin Netanyahu has appointed opposition lawmaker Gideon Sa'ar to rejoin his cabinet, the politicians announced in a joint statement Sunday.
Sa'ar will serve in the Security Cabinet, according to Netanyahu.
"I appreciate the fact that Gideon Sa'ar responded to my request and agreed today to return to the government," Netanyahu said, noting how the leaders have put aside their disagreements.
"We will work together, and I intend to use him in the forums that influence the conduct of the war," Netanyahu added.
Sa'ar was once a member of Netanyahu's Likud Party but defected after an unsuccessful bid for party leadership. He formed his own party in 2020 called New Hope.
"I am joining the government at this stage without a coalition agreement - but with an orderly worldview and with a strong patriotic attitude for our people," Sa'ar said in the joint statement.
The Israel Defense Forces said it carried out a large-scale air operation against military targets belonging to the Houthis in Yemen on Sunday.
Yemen's state news agency said four people have been killed and 49 others injured.
The IDF blamed Iranian transfers of weapons, supplies and oil to the Houthis, and said the attack was "in response to the recent attacks by the Houthis" against Israel.
The IDF chief of general staff, Herzi Halevi, said of the strikes, "This is not a message -- it is an action. An action that carries a message with it."
This strike was coordinated with the U.S., but was only an Israeli operation, a senior Israeli source told ABC News.
