Iranian FM Abbas Araghchi met Russian President Vladimir Putin at the Boris Yeltsin Presidential Library in St. Petersburg — the culmination of Araghchi's Islamabad-Oman-Islamabad-Moscow regional tour. Putin delivered his strongest statement of solidarity since the war began: "We see how courageously and heroically the Iranian people are fighting for their independence, for their sovereignty. Russia will do everything that meets your interests and the interests of all peoples in the region in order to ensure that this peace is achieved as quickly as possible." Kremlin spokesman Dmitry Peskov said beforehand: "The significance of this conversation is hard to overestimate in terms of how the situation around Iran and in the Middle East is developing." Araghchi responded on X: "Pleased to engage with Russia at the highest level as the region is in major flux. Recent events have evidenced the depth and strength of our strategic partnership. As our relationship continues to grow, we are grateful for solidarity and welcome Russia's support for diplomacy." Araghchi also said of Oman that the two countries had "reached some agreements" focused on the Strait of Hormuz, and emphasised: "As the two coastal countries of this strait, we must speak with each other so that our common interests are secured." At the UN Security Council, Russia's ambassador attributed Hormuz insecurity to Western "lawless" actions — sanctions and seizures. China's ambassador said the root cause was illegal US-Israeli military actions. Russia and China had previously vetoed a UNSC draft resolution seeking freedom of navigation through Hormuz. Rubio confirmed Khamenei is "still alive" per US indications but questioned his power: "Alive and in power are two different questions." Reuters separately cited unnamed sources that Khamenei is joining major war decisions including negotiations via audio conferencing.
Multiple sourced reports — AP, CNBC, CNN, Fortune, Fox News — confirmed the full contents of Iran's peace proposal passed via Pakistan: a staged process in three phases. Phase 1: the US and Israel formally end the war on Iran, with binding guarantees that Washington could not restart it. Phase 2: both sides simultaneously end their respective blockades — Iran reopens the Strait of Hormuz without restrictions or tolls; the US lifts its naval blockade of Iranian ports. Phase 3: only then would nuclear negotiations begin — Iran still seeking US acknowledgment of its right to enrich uranium for what it calls peaceful purposes. Critically, nuclear issues were explicitly postponed to a later stage. Iran also separately passed written "red lines" via Pakistan's Fars News Agency, covering nuclear issues and the Strait of Hormuz. Iran floated a separate mechanism to collect tolls from vessels passing through the strait — a regional official told Reuters/AP that Iran was trying to persuade Oman to support this; Oman's response was not immediately clear. Araghchi on Saturday had posted on X that he had shared "Iran's position concerning workable framework to permanently end the war" and added: "Have yet to see if the U.S. is truly serious about diplomacy." CNN sources confirmed intense backchannel diplomacy was ongoing and described the next few days as "especially crucial" — with a staged agreement focused on returning to the pre-war status quo on Hormuz seen as the most viable first step. Trump was described as "unlikely" to accept the proposal as framed. White House press secretary Leavitt confirmed Trump met his NSC on the Iran proposal.
The White House confirmed Trump met his national security and foreign policy team Monday to discuss Iran options — two US officials told ABC News the meeting included discussion of whether the US would resume its bombing campaign. Leavitt confirmed Trump and his team had discussed Iran's latest proposal. Secretary of State Rubio gave the clearest US rejection of Iran's nuclear deferral framing in a Fox News interview: "Iran's nuclear ambitions are the central issue in any negotiations with the US." He added: "We can't let them get away with it. We have to ensure that any deal that is made, any agreement that is made, is one that definitively prevents them from sprinting towards a nuclear weapon at any point." Rubio's stance directly contradicted Iran's proposal to postpone nuclear talks. Trump also signalled he was unlikely to accept Iran's offer, which would leave the nuclear questions unresolved. At the United Nations Security Council, National Security Advisor Mike Waltz delivered a sharp statement on the Hormuz standoff: "This strait is not Iran's to wield like its own moat and drawbridge. It is not Iran's hostage. It is not Iran's bargaining chip. It is not Iran's toll road." UN Secretary-General Guterres said his office was ready to help the warring parties reach an agreement to reopen the strait. Hezbollah Deputy Secretary-General Naim Qassem separately declared Israel-Lebanon negotiations a "grave sin": "We categorically reject direct negotiations with Israel, and those in power should know that their actions will not benefit Lebanon or themselves." Araghchi blamed the US from St. Petersburg: "The US approaches caused the previous round of negotiations, despite progress, to fail to reach its goals because of the excessive demands."
Brent crude traded at approximately $108/barrel on Monday — nearly 50% above its pre-war level, confirming the conflict was now the largest sustained oil price shock since the 1970s. CENTCOM confirmed 38 vessels had been redirected as of Sunday night — up from 37 on Saturday. MarineTraffic data showed Hormuz shipping at near-standstill, with "only a handful of crossings reported Sunday," though CNN noted the data can be affected by signal gaps and AIS spoofing. Thousands of seafarers remained trapped in the Gulf, unable to safely transit the strait. UK Prime Minister Keir Starmer and Trump held a call — Downing Street confirmed the two leaders discussed the "urgent need" to get shipping moving again through Hormuz; Starmer warned of "major global economic and cost-of-living impacts." Iran's midterm election pressure was noted by Euronews — fuel prices rising ahead of November midterms were creating domestic political pressure on Trump. The AP confirmed a cumulative casualty toll for the war as of April 27: at least 3,375 killed in Iran; at least 2,521 in Lebanon; 23 in Israel; more than a dozen in Gulf Arab states; 16 Israeli soldiers in Lebanon; 13 US service members; 6 UN peacekeepers. Brent's $108 level represented the global economic cost being borne by consumers, shipping companies, and governments worldwide — with the IEA's two-year LNG disruption forecast from Qatar adding to the long-term energy market damage.
The Iran proposal is the most concrete diplomatic offer since the war began — but it is structured to give Iran its primary strategic need (end the war with guarantees) before addressing the US's primary demand (nuclear). Rubio's immediate flat rejection of nuclear deferral means the gap is as wide as ever at the public level. Yet CNN's sources say intense backchannel diplomacy continues and the next few days are "especially crucial" — suggesting the US public rejection may be a negotiating position rather than a final answer. Putin's "courageously and heroically" language is the strongest Russian wartime solidarity statement since the conflict began and signals Moscow intends to remain Iran's diplomatic backstop at the UN. The Hormuz toll scheme Araghchi floated with Oman is a new element — Iran trying to convert IRGC maritime control into a permanent revenue stream even before a deal, which would be unacceptable to the US and Gulf states. At $108 Brent and 38 ships redirected on Day 60, the economic war is now deeper than the original 1973 oil embargo in proportional impact. The Khamenei audio conferencing report is the most significant intelligence update on Iran's command structure since the NYT leg surgery revelations — it means Iran's supreme leadership is engaged, not incapacitated, but operating in a way designed to prevent physical location tracking by Israeli intelligence.
