Secretary of State Marco Rubio and Lebanon’s President Joseph Aoun held a call on Friday, during which Rubio "reiterated that Hizballah is entirely responsible for the ongoing fighting” in the country, according to the U.S. State Department.

The readout makes no mention of the ceasefire agreement between Lebanon and Israel but says Rubio "commended President Aoun’s courage and vision in pursuing direct negotiations with Israel” during their conversation.

Negotiations between Lebanon and Israel are set to resume in Washington next week.

Negotiations between Iran and the U.S. are still ongoing and a text for a memorandum of understanding, an agreement, "has not yet been finalized," Iran’s Foreign Ministry said Friday.

"What the Americans refer to as a 'maritime blockade' was an illegal action from the very beginning, both a violation of the ceasefire and an obstruction of international freedom of navigation. We need to see in practice whether they will actually follow through on this statement or if it is merely a propaganda claim," Esmaeil Baqaei, spokesperson for Iran's Ministry of Foreign Affairs, told Iran’s State TV Friday.

"Regarding an agreement, as I said, as I speak to you now, message exchanges are continuing, but no final agreement has been reached," he said.

Iranian officials said negotiations with the U.S. are focused on ending the war imposed on Iran and nuclear issues are not being discussed in detail at this stage, according to Iranian Press TV.

The Strait of Hormuz has been under Iran's special measures since the imposed war began and is closed to hostile military vessels, however, commercial ships have transited through the route in coordination with Iranian authorities, according to Iranian Foreign Ministry spokesperson Esmail Baghaei.

Baghaei also said Iran and Oman must establish mechanisms that both preserve their national interests and security as well as reassure the international community that shipping through this route is conducted safely.

The Israel Defense Forces said on Sunday that its troops operating in southern Lebanon had advanced north of the Litani River and secured the Beaufort Ridge -- a strategic position south of the Lebanese city of Nabatieh.

"The IDF crossed the Litani River and expanded the strikes on Hezbollah north of the river. The activity is expanding to additional areas at this moment," the IDF said in a post to X.

"The IDF is operating near Nabatieh, which constitutes a significant power center of the Hezbollah terror organization in southern Lebanon, and is prepared and ready to expand the attack as required," the force added.

Israeli Defense Minister Israel Katz said the advance was made "at the direction" of Israeli Prime Minister Benjamin Netanyahu. "The campaign is not yet over. The IDF is strong, and we are all determined to crush Hezbollah's power and complete the mission: ensuring security for the residents of the North," Katz wrote on X.

Also on Sunday, IDF spokesperson Avichay Adraee issued an evacuation order for all residents of southern Lebanon, particularly those south of the Zahleh River.

The Israeli offensive in southern Lebanon -- and airstrike campaign in the south and east of the country, plus in the capital Beirut -- is ongoing despite a ceasefire agreed between Israeli and Lebanese leaders in April.

Lebanon's Ministry of Public Health said that as of Saturday, 3,371 people had been killed and 10,129 people wounded by Israeli strikes since March 2.

Lebanese Prime Minister Nawaf Salam on Saturday accused Israel of adopting a "scorched-earth policy" in its campaign against Hezbollah. Salam said the IDF was engaged in "collective punishment" of southern Lebanese communities by "destroying towns and villages, and forcing their inhabitants into exile."

Hezbollah, meanwhile, continues its attacks on Israeli soldiers deployed in the south of Lebanon and its long-range strikes on northern Israel.
