Israeli Prime Minister Benjamin Netanyahu's Office accused Hezbollah of violating the ceasefire agreement by attacking soldiers in the security zone.

"The Hezbollah attack seriously injured three of our soldiers. The [Israel Defense Forces] responded by striking the Hezbollah terror headquarters which ordered the attack," Netanyahu's office said.

Netanyahu's office said the IDF only learned after the strikes on the headquarters that "Hezbollah deliberately put civilians in that military compound."

"Hezbollah is willing to do anything, including using its own civilians as human shields, to falsely accuse Israel of deliberately targeting civilians, which the IDF clearly did not," Netanyahu's office said.

In a separate statement released Saturday, the IDF says a Hezbollah battalion commander was killed when it struck the Hezbollah headquarters in the Ansar region of Southern Lebanon.

Ali Samir Al-Haj Hassan, a Hezbollah commander in the Radwan Force unit, was killed alongside "several additional terrorists who were involved in advancing terror attacks against IDF," according to the statement.

The IDF also states Hassan's family were present in the Hezbollah headquarters during the strike and were "harmed."

The United Arab Emirates is condemning the latest attack on a vessel crossing the Strait of Hormuz, UAE's Foreign Ministry said Saturday.

The Ministry of Foreign Affairs called it a "hostile Iranian attack" targeting a ship associated with the Abu Dhabi National Oil Company (ADNOC). The Emirates News Agency said the company confirmed the incident occurred on Friday evening and no injuries were reported.

This comes after two ADNOC ships were targeted on Thursday.

At least nine people are dead and 11 others injured in Israeli strikes on two towns in southern Lebanon, the Lebanese Ministry of Health said Saturday.

Seven were killed and two others wounded in a strike in the town of Ansar, the ministry said. Three children and 2 women were among the dead according to authorities.

Another Israeli strike left two dead and nine injured in the town in Der al-Zahrani, the health ministry said.

In a statement, the Israel Defense Force said the strikes on "terror infrastructure" were in response to action against its soldiers by Hezbollah.

"The IDF will not allow the Hezbollah terrorist organization to harm Israeli civilians and IDF soldiers, and will continue to operate to remove threats," the IDF statement said.

Lebanon Prime Minister Nawaf Salam said the escalation "undermines efforts to stabilize the situation in the south."

"The seven martyrs of the Israeli airstrike on the town of Ansar are not 'military infrastructure,' nor are the children and women killed in it military targets," Salam said.

Israel and Lebanon have been in talks since signing a "framework agreement" in June.

Despite the truce, the Israeli military has continued to strike Hezbollah targets and remains present in southern Lebanon.

Lebanon's president Joseph Aoun condemned Saturday's attacks, calling them violations and "a clear message to the negotiation track and to the American efforts aimed at implementing this agreement," the Lebanese president's office said in a statement.

Israel has vowed to remain in southern Lebanon until Hezbollah is disarmed.

Iran's deputy foreign minister for legal and international affairs, Kazem Gharibabadi, posted a response on social media to President Donald Trump's statement that the Strait of Hormuz would be declared a U.S. territory after Iran is defeated.

"The Strait of Hormuz cannot be seized by tweet, nor by aircraft carrier, nor by issuing an order, nor by an election speech. Iran neither fears threats nor cowers before displays of power," he said.

He added that, "the Strait of Hormuz has been Iranian, is Iranian, and will remain Iranian; this strait will only be closed and opened under Iran's command, and as long as you do not accept the reality of defeat and cease your fanciful delusions, Iran will continue to enforce the blockade."
