U.S. envoy Tom Barrack held talks Monday in Israel with Prime Minister Benjamin Netanyahu and other top Israeli officials.

The talks were to focus on preventing escalation in Syria and Lebanon, media reports said prior to the meeting.

Army Commander General Rodolphe Haykal and a delegation of Arab and foreign ambassadors and military attachés arrived Monday at the Tyre barracks at the start of a tour organized by the Lebanese Army to brief them on the implementation of the disarmament plan in the South Litani sector and Israel’s attacks.

They were received by the commander of the South Litani sector, Brigadier General Nicolas Tabet.

Israeli army spokesperson Avichay Adraee criticized "Hezbollah's supporters" who attacked Lebanese President Joseph Aoun after the latter condemned a mass shooting at a Jewish holiday event that killed at least 11 people in Sydney.

Adraee said those who "live on the rhetoric of death see a threat in every humanitarian stance."

Israeli army chief Eyal Zamir has conducted a situation assessment at Israel's Northern Command.

“In a short period, we eliminated the Hezbollah commander (Haitham Tabatabai) and the head of Hamas' manufacturing division. We will not allow the enemy to expand and will respond to any violation of the agreement. Our policy is clear, in all arenas, and here in Lebanon -- we will continue to act and thwart threats before they develop,” Zamir told troops and officers.

Ali Akbar Velayati, the international affairs advisor to Iran's supreme leader, met with Hezbollah’s representative in Iran Abdallah Safieddine on Sunday and stressed that Tehran will continue to firmly support Hezbollah.

Hezbollah is “one of the most important pillars of the resistance front and is playing a key role in confronting Zionism,” Velayati said.

A senior adviser to Iran's supreme leader said Sunday that the country would "resolutely support" Hezbollah, its ally in Lebanon, in the group's efforts to confront Tehran's regional foe Israel.

The remarks by Ali Akbar Velayati came as Lebanon faces pressure from the United States and Israel to disarm Hezbollah, which engaged in more than a year of hostilities with Israel following the outbreak of the Gaza war.

The Israeli military said it killed three Hezbollah members in strikes Sunday on southern Lebanon, where it has carried out repeated attacks despite an ongoing ceasefire with the Iran-backed group.

The Lebanese health ministry said three people were killed in strikes in the Yater, Safad Al-Battikh and Jwaya areas of the south.

Israel resumed drone strikes on south Lebanon on Sunday, after an apparent suspension that followed its assassination of Hezbollah military chief Haitham al-Tabatabai in a Beirut southern suburbs raid.

The Israeli military said it would "temporarily" suspend a strike planned for Saturday that was intended to target what it described as Hezbollah military infrastructure in southern Lebanon.

President Joseph Aoun has said that the latest remarks attributed to U.S. envoy Tom Barrack are "rejected by all Lebanese."
