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.

Several U.S. troops and civilian contractors suffered minor injuries and have since been returned to duty following an Iranian missile attack intercepted over Ali Al Salem Air Base in Kuwait on Wednesday, a U.S. official told ABC News.

The injuries came from falling debris from the interception. It’s unclear how many troops were wounded, according to the official.

As of Friday, 409 troops have been wounded in the war with Iran accord to Pentagon data, much of that being traumatic brain injuries.

Authorities in Oman issued an alert Saturday, warning vessels to exercise caution after an "object suspected to be a floating mine" was spotted in the Strait of Hormuz.

The object was reported in the Inshore Traffic Zone within Omani territorial waters, Oman's Maritime Security Center said in a post on X.

It is unclear if the suspected object had been recovered.

"All maritime users are advised to keep a safe distance from any suspicious objects and report them immediately to the relevant authorities," the post said.

A post from Oman's Ministry of Defense said "to exercise the utmost caution and vigilance while navigating, following the detection of a floating object suspected to be a sea mine west of the coastal traffic area."

Hamas called on several countries represented in the Peace Council to speak out against Israeli Prime Minister Benjamin Netanyahu's comment that Israel now controls 60% of the Gaza Strip.

"We strongly condemn the complete silence of the so-called Peace Council and its Executive Director, Mladenov, regarding the dangerous statements issued by the occupation government concerning its intention to take control of 70% of the Gaza Strip and continue pursuing plans of displacement," Hamas spokesperson Hazem Qassem said in a statement.

"Ignoring these aggressive statements and failing to condemn the occupation's expansionist policies and forced displacement plans raises serious questions about the extent of the sponsoring parties' commitment to holding the occupation accountable to its obligations and putting an end to its ongoing violations and breaches," Qassem added.

Monday's strikes in Iran were prompted by the U.S. detecting a pattern of increasing and potentially threatening Iranian activity over a 24-hour period, according to a U.S. official.

U.S. Central Command had said Monday that U.S. forces "conducted self-defense strikes in southern Iran to protect our troops from threats posed by Iranian forces."

"Targets included missile launch sites and Iranian boats attempting to emplace mines," it said.
