Hezbollah leader Sheikh Naim Qassem said on Thursday that his Iran-backed group would "act as we see fit" in response to the ongoing war between Iran and Israel.

In a written statement, Qassem said Hezbollah was "not neutral" in the conflict between the two regional superpowers, saying that the group would "act as we see fit in the face of this brutal Israeli-American aggression."

Hezbollah will not join the fray in the Israeli-Iranian war, a Lebanese government source told al-Jadeed Thursday, after an Iranian official told al-Jazeera that Hezbollah would act if the United States intervened to back up its ally Israel.

"The communication between the Lebanese Army and Hezbollah is reassuring," the source said, ruling out such a possibility.

Israeli Prime Minister Benjamin Netanyahu said Thursday that the entire "Shiite axis" including Hezbollah is not responding to Israeli attacks on Iran.

"Hezbollah has not fired a single rocket," Netanyahu said, vowing to "remove" the nuclear and ballistic missile threat posed by Iran, on the seventh day of war between the arch foes.

President Joseph Aoun on Thursday told visiting U.S. envoy Tom Barrack that contacts are ongoing to address the issue of the arms of Hezbollah and the Palestinian factions in Lebanon, adding that the talks will intensify “after the stabilization of the situation in the region which deteriorated due to the escalation of the Israel-Iranian conflict.”

Hezbollah condemned Thursday Israel's threats to kill Iran's supreme leader Ayatollah Ali Khamenei after an Israeli hospital was hit during an Iranian missile attack.

"Khamenei openly declares that he wants Israel destroyed -- he personally gives the order to fire on hospitals. He considers the destruction of the state of Israel to be a goal," Israel's defense minister Israel Katz told journalists in Holon near Tel Aviv. "Such a man can no longer be allowed to exist."

An Israeli strike on the southern town of Kfarjoz in Nabatieh killed one person overnight, with Israel saying he was "the head of Hezbollah's anti-tank unit in Shebaa."

Media reports said another person, standing on the balcony of his house near the strike, later died of his injuries.

The Free Patriotic Movement said Wednesday that Lebanon should not take part in the Israeli-Iranian conflict as the arch foes traded fire for the sixth day.

"The war in the region is concerning and is threatening peace and stability in the region and in Lebanon," the statement said, describing the Israeli strikes on Iran as an aggression and condemning it. "The FPM is against any aggression on the sovereignty of any county."

Under-Secretary-General for U.N. Peace Operations Jean-Pierre Lacroix met Wednesday in Lebanon with President Joseph Aoun and Speaker Nabih Berri.

An Israeli interception missile landed Wednesday afternoon in a valley between the Tyre district towns of Barish and Maaroub, the state-run National News Agency reported.

An Israeli drone on Wednesday dropped leaflets resembling fake currency over the southern town of Aitaroun, the National News Agency said.
