The U.S.-Iran memorandum of understanding is due to be signed on Friday.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Following the announcement of a two-week ceasefire, initial U.S.-Iran talks in Pakistan in April failed to reach a peace deal. Trump later announced the open-ended extension of the ceasefire and the continuation of a U.S. blockade until negotiations concluded.
On Sunday, Trump announced that the U.S. and Iran had reached a "great deal," which he said would be signed on Friday.
Iran's Islamic Revolutionary Guard Corps accused Israel of violating the ceasefire in southern Lebanon "84 times in the past two days" after President Donald Trump "declared the end of the war," Iran's semi-official Fars News Agency said Tuesday.
The IRGC warned that if Israel does not end its military attacks on southern Lebanon, it should expect a "harsh response" from Iran.
The Israel Defense Forces said its Air Force intercepted "several rockets" that were launched by Hezbollah toward the area in which the IDF is operating in southern Lebanon on Tuesday.
"Shortly afterward, the Israeli Air Force struck and dismantled the launcher from which some of the rockets were fired toward IDF soldiers in southern Lebanon," the IDF said in a statement to ABC News.
Israel asked the U.S. to see the memorandum of understanding, but the request was denied, according to an Israeli source and a U.S. official familiar with the matter.
The officials confirmed that the Israeli government has been thoroughly briefed on the MOU's contents.

Iranian Foreign Minister Abbas Araghchi said on Tuesday that the new round of negotiations between Iran and the U.S. for a final peace agreement will start the day after signing the memorandum of understanding, according to the semi-official Fars News Agency.
Iranian Deputy Foreign Minister Majid Takht-Ravanchi said Tuesday that the speaker of the Iranian parliament, Mohammad Bagher Ghalibaf, will travel to Geneva to officially sign the MOU, as quoted by the official Islamic Republic News Agency.
Speaking of potential Israeli breaches of the MOU in Lebanon, Takht-Ravanchi said that "a mechanism that has been foreseen in the memorandum of understanding will be activated." Takht-Ravanchi did not offer further details on the mechanism.
The U.S., he said, had committed to bringing the war to an end on all fronts, including in Lebanon, "on behalf of its partners in the MOU."
