Hezbollah considered Wednesday the U.S. "a full partner to the Israeli aggression on Gaza," holding it fully responsible for the killing, siege, destruction, and massacres "against defenseless civilians, including children, women, and elderly."

"We were not surprised by the U.S. support for the Zionist aggression against the Palestinian people," Hezbollah said in a statement.

U.S. Ambassador to Lebanon Dorothy Shea met Tuesday with Speaker Nabih Berri and caretaker Prime Minister Najib Mikati to “relay the U.S. stance” over the developments in Gaza and south Lebanon, media reports said.

Shea “warned against dragging Lebanon or Hezbollah’s entanglement of the country through opening a new front in the South,” al-Liwaa newspaper reported on Wednesday.

A potential intervention by Hezbollah and uncertainty over the role played by Iran itself are risk factors that could push the unprecedented conflict between Israel and Hamas into a wider regional war, analysts say.

For now, there is no indication of an impending offensive by Hezbollah against Israel, despite growing border tensions.

Lebanese Forces leader Samir Geagea has said in an interview with MTV that the Lebanese opposition will “exert utmost effort” to prevent a major ignition of Lebanon’s southern front with Israel.

“We can do without adding to all the miseries of the Lebanese people,” Geagea said.

Israel is not interested in starting a war with Hezbollah but is ready to fight if necessary, Asharq al-Awsat newspaper reported Wednesday.

The daily claimed that Israel has sent this message to Hezbollah through France on Saturday and that Hezbollah responded that it is too "not concerned" with starting a war but is ready for it if necessary.

Free Patriotic Movement chief Jebran Bassil has warned against a return to the so-called “Fatah Land” era in south Lebanon, in the wake of the attacks launched by Palestinian groups Hamas and Islamic Jihad from south Lebanon.

“As much as we support the right of the Palestinian resistance to fight Israel on Palestine’s land, we refuse any use of Lebanese territory as a launchpad for military actions by any non-Lebanese party,” Bassil said on a post on the X platform.

Israel shelled south Lebanon Wednesday after Hezbollah fired rockets from the border area, the latest exchange on Israel's northern border as it battles Hamas militants in Gaza.

"The area around Dhayra is being bombarded by enemy artillery, while the area around Yarin is being hit with phosphorus shells," Lebanon's National News Agency said, earlier reporting "two rockets fired from Lebanese territory".

A fresh salvo of rockets was fired from south Lebanon towards Israel on Tuesday, prompting Israeli attacks on positions belonging to Hezbollah and retaliatory fire, in the third consecutive day of cross-border tensions.

The rocket launch, which was claimed by Hamas' armed wing, comes amid a raging war between Israel and the Hamas in and around the Gaza Strip.

In mosques, football stadiums and towns across the Arab world, pro-Palestinian sentiment has surged after a shock Hamas attack on Israel, sparking a groundswell of solidarity for the Palestinians.

From Ramallah to Beirut, Damascus, Baghdad and Cairo, people have distributed sweets, danced and chanted prayers in support of the "resistance" to Israel's long-standing occupation of Palestinian land.

Hezbollah will “certainly respond” to the Israeli shelling that killed three of its members in south Lebanon on Monday, Hezbollah sources told al-Joumhouria newspaper in remarks published Tuesday.

Sources close to the group meanwhile told the daily that Hezbollah is maintaining the highest level of preparedness for any development, while denying the reports about Hezbollah “messages” sent to Israel through Arab sides.
