A senior Iranian army official warned Saturday that Israeli strikes on Beirut would not go “unanswered,” deepening the crisis on the same day President Donald Trump declared a nuclear peace deal with Iran could be signed by Sunday.

Iran's lead nuclear negotiator told state media that Washington lacks the willingness to fulfil its commitments, directly contradicting Trump's public optimism about an imminent agreement.

Trump made the claim at the White House Saturday, saying the Strait of Hormuz — closed to international shipping amid the standoff — would reopen shortly after a deal is signed.

The competing signals from Tehran and Washington came as Beirut absorbed what Israeli officials described as targeted strikes on Hezbollah infrastructure. Iran regards those strikes as an attack on its regional allies and has declined to publicly separate the Beirut situation from the nuclear file.

No signing date or venue for a nuclear agreement has been confirmed by either government. Iranian state television has not scheduled any address by senior leadership.

If talks hold, a further round of negotiations is expected before any text reaches final signature stage. Trump's self-imposed Sunday deadline has not been acknowledged by Iranian officials.
