United States President Donald Trump on Sunday condemned Israel's attack on Beirut, Lebanon's capital, stating it "should not have happened" on a day when a deal to end the US-Israel war with Iran was reportedly close to being signed. The condemnation came via a post on Trump's social media platform, Truth Social.

Trump emphasized the critical juncture for peace, asserting, "We are very close to a Deal that will bring peace to the region, including to Lebanon, and all sides should stand down." He called for an end to hostilities from all parties, stating, "There should be no more attacks by Israel anywhere in Lebanon, but there should also be no more attacks by any other party, including Hezbollah, against Israel."

Authorities reported at least three fatalities from the Israeli strikes in Beirut's Dahiyeh area. The Israeli military stated the operation was a response to Hezbollah launching projectiles toward northern Israel. However, Trump questioned the proportionality of Israel's response, describing the Hezbollah attack as "very small and meaningless, nobody was hurt, injured, or killed, and should not disrupt this important process."

The potential peace deal aims to conclude the 12-day war that began with US and Israeli attacks against Iran, following indirect talks concerning Iran's nuclear program. Trump had previously announced on Saturday that a deal with Iran was "scheduled" for signing on Sunday, with Pakistan, a key mediator, suggesting a digital signing process.

Iranian officials, however, presented a slightly different timeline. Esmaeil Baghaei, a spokesperson for Iran’s Ministry of Foreign Affairs, indicated on Saturday that the signing might take several days to finalize. Despite the minor discrepancies in timing, both the US and Iran have broadly signaled that an agreement to cease hostilities on all fronts, including in Lebanon, is imminent.

Mohammad Bagher Ghalibaf, Iran's top negotiator and parliament speaker, reacted to the Beirut strikes by questioning US commitment. In a post on X, Ghalibaf stated that the US "either lacks the will to fulfil its commitments or the ability to do so." He further added that if the US cannot uphold its promises, "speaking of continuing the path is not possible."

The ongoing conflict, which began on February 28, has seen both the US and Israel launch attacks against Iran. These actions have escalated tensions and complicated diplomatic efforts aimed at resolving the broader regional instability and Iran's nuclear program.

The situation remains fluid, with the success of the peace deal now contingent on de-escalation from all parties involved and the resolution of trust issues highlighted by the recent military actions. The coming days are expected to be crucial in determining whether the fragile path towards regional peace can be successfully navigated.
