A landmark agreement between Washington and Tehran appears imminent, with multiple sources confirming the broad outlines of a nuclear and sanctions deal brokered in part through Pakistani mediation. However, the signing timeline has been thrown into uncertainty following an Israeli military strike on Beirut's southern suburbs, which U.S. President Donald Trump publicly criticized, complicating the diplomatic momentum at a critical juncture.

Details:

According to Al-Jazirah, President Trump formally announced via his Truth Social platform that an agreement had been reached with Iran, stating the deal fulfills the primary objective of his administration regarding Tehran's nuclear ambitions. The publication reports that the framework includes suspension of sanctions, nuclear restrictions, and the release of frozen Iranian assets — details corroborated by Al-Watan, which noted that a senior Iranian official confirmed Tehran had agreed, under the memorandum of understanding, not to produce or possess nuclear weapons.

Alyaum reports that Iran's National Security Council announced the signing ceremony was scheduled for the coming Friday, while Trump himself stated the deal remained on track and was expected to be signed within hours. U.S. Vice President JD Vance separately addressed questions regarding whether Trump would attend the signing in person, without offering a definitive confirmation, according to Alyaum.

However, Al-Watan indicates the Israeli strike on Beirut's southern district significantly disrupted the diplomatic calculations of both Washington and Tehran. Iran's chief negotiator and parliamentary speaker Mohammad Baqer Qalibaf stated the Israeli attack on the suburb had complicated the diplomatic process. Trump, for his part, described the Israeli strikes as a "damn attack," a characterization reported by Alyaum, signaling unusual public friction between Washington and Tel Aviv at a sensitive moment.

Former U.S. President Barack Obama, cited by Alyaum, expressed skepticism that any new agreement with Iran would surpass the 2015 nuclear accord, adding a layer of domestic American political commentary to an already complex international negotiation. Meanwhile, Al-Jazirah reports that British forces intercepted a sanctioned Russian shadow fleet oil tanker in the English Channel, underlining that global geopolitical pressures extend well beyond the Iran file.

Watch For:

— Whether the U.S.-Iran signing ceremony proceeds by Friday as announced by Tehran's National Security Council, or whether Israeli military operations in Lebanon force a further postponement or substantive renegotiation of terms.

— The specific scope of sanctions relief and uranium enrichment restrictions in the final text, as Al-Jazirah's sourcing indicates Washington agreed to allow the reduction — not full elimination — of highly enriched uranium stockpiles inside Iran.

— Israel's posture in the coming days, given Trump's public rebuke of the Beirut strikes and the potential for further Israeli unilateral action to derail U.S.-brokered regional diplomacy.
