Israeli Prime Minister Benjamin Netanyahu said on Monday that Israel's forces would remain in Gaza, Lebanon and Syria "for as long as necessary," hours after a deal was announced between Iran and the U.S. to end the Middle East war.

Hezbollah said on Monday it had repelled an Israeli force that was trying to "advance" in southern Lebanon, despite the U.S.-Iran agreement to end the Middle East war on all fronts including in Lebanon.

The Iran-backed group said the attack came in response to Israel's violation of the ceasefire on Monday.

President Joseph Aoun on Monday welcomed the announced U.S.-Iran deal to end the Middle East war during a call from Tehran's top diplomat and foreign minister Abbas Araghchi, the Lebanese presidency said in a statement.

The Lebanese leader said he hoped the agreement would be a "positive step towards reducing tensions and opening the door to diplomatic solutions," while Araghchi emphasized "the importance of respecting Lebanon's sovereignty and territorial integrity by all parties," the statement said.

When Kamal Kamal heard a ceasefire deal had been agreed between Iran and the United States, he rushed back to the southern city of Nabatieh only to find an Israeli strike had reduced his life's work to rubble.

A deal between Washington and Tehran that ends the Israel-Hezbollah war leaves many issues in Lebanon unresolved, failing to mention Israel withdrawing from the country or an end to Tehran's support for the militant group.

MP Hussein al-Hajj Hassan on Monday said that Hezbollah and Speaker Nabih Berri have been informed by Iran that Israeli withdrawal is included within the "framework of the agreement" with the U.S. and that "its details will be discussed soon."

Prime Minister Nawaf Salam hoped Monday that the ceasefire agreement reached by the U.S. and Iran will succeed in "ending this war and halting the killing, destruction, displacement and all the other tragedies and suffering inflicted upon the Lebanese people."

The U.S.-Iran agreement to conclude the Middle East war is a significant strategic setback for Israel and underscores its waning influence in Washington, Israeli analysts said.

Although the accord, announced by Pakistan early Monday, remains incomplete and is expected to be finalized within 60 days, its preliminary framework has already raised concern in Israel.

Hezbollah thanked its backer Iran on Monday for insisting that Lebanon, where Israel and the militants have been at war, be included in the deal to end the Middle East conflict.

"Hezbollah expresses its profound gratitude" to Iran's leaders, forces and people "for their steadfast support of Lebanon, its people and its resistance, and for their insistence that Lebanon be included in any understanding leading to the cessation of war", the group said in a statement.

Iran's foreign ministry on Monday said the United States must ensure that Israel commits to stopping the war in Lebanon under a framework deal to end the Middle East war.

"The United States must honor its commitments. It must ensure that the Zionist regime also respects its own regarding Lebanon," said foreign ministry spokesman Esmaeil Baqaei in a press briefing, adding that Tehran "neither trusts Israel nor the United States".
