Israel's far-right national security minister, Itamar Ben Gvir, on Monday denounced the deal between the United States and Iran to end the Middle East war, including in Lebanon, insisting his country was not bound by it.

"Trump's agreement does not bind us... we are not party to this agreement. It does not safeguard our security," Ben Gvir said on his Telegram channel, in what was the first reaction from an Israeli official to the deal.

Pakistan's prime minister announced that the United States and Iran had agreed to a "Peace Deal" that immediately halts all military operations, including in Lebanon, with a signing ceremony to take place in Geneva on June 19.

U.S. President Donald Trump said Sunday that a peace deal with Iran is "now complete," announcing the Strait of Hormuz is open and the United States will lift its naval blockade.

"The Deal with the Islamic Republic of Iran is now complete. Congratulations to all!," Trump said on his Truth Social network, shortly after mediator Pakistan said both sides had reached an agreement.

Iran's highest national security body warned on Sunday that a response was "imminent" following an Israeli strike targeting Tehran's ally Hezbollah in Beirut's southern suburbs.

The Israeli military said Sunday that its forces had killed a senior Hezbollah militant accused of involvement in the kidnapping and killing of five American soldiers in Iraq in 2007.

U.S. President Donald Trump said Sunday that a peace deal with Iran was still on track to be signed within hours, despite an Israeli strike on Beirut's southern suburbs that he said had delayed the plan.

Iran said on Sunday there was "no point" in peace talks with the United States, accusing it of failing to uphold its commitments and casting doubt on a deal that Donald Trump had insisted would be signed imminently.

Lebanon's foreign ministry said it had lodged a complaint with the United Nations over Israel's alleged spraying of herbicide glyphosate in Lebanese territory near the border earlier this year.

The office of Israeli Prime Minister Benjamin Netanyahu said on Sunday the military had carried out a strike in Beirut's southern suburbs, known as Dahieh, while Lebanese state media said a strike hit the Ghobeiry neighborhood, killing three people, wounding 15 others and causing extensive damage to buildings and shops.

The Israeli military said three drones, suspected to have been launched by Hezbollah from Lebanon, struck northern Israel in separate incidents on Sunday, causing no casualties.
