Foreign minister Abbas Araghchi says compliance with the US-Iran memorandum of understanding must be mutual. Tehran denies seeking new talks with Washington, but says it will accept a Qatari mediation visit.

Khamenei's flag-draped coffin was carried into the Imam Reza shrine in his hometown of Mashhad, where state television said he was buried in a memorial hall following prayers attended by thousands of mourners.

Attacks hit southern Iran as funeral rites for the slain supreme leader continued in Iraq, prompting Tehran to accuse Washington of breaching their memorandum of understanding.

The latest incident follows weeks of escalating tensions over a US-backed maritime corridor through Omani territorial waters, a route Iran has repeatedly rejected.

Organizers said the procession is expected to last between 10 and 12 hours along a roughly 10-kilometre route passing through Tehran's central squares and avenues before Khamenei's body is flown to the holy city of Qom for further funeral rites.

The prayers were attended by President Masoud Pezeshkian, senior military commanders and members of Khamenei's family, although his successor, Mojtaba Khamenei, remained absent over security concerns.

The funeral of Iran's assassinated supreme leader has drawn mourners and foreign delegations from more than 100 countries, with Tehran presenting the ceremony as a display of national unity and political continuity following the US-Israeli strikes that killed him.

Millions are expected to gather in the Iranian capital over the coming days, with senior regional leaders attending ceremonies that Tehran hopes will project resilience before indirect negotiations with Washington resume.

The warning came as US-Iran diplomacy remained on track after Doha talks. Iran's deputy foreign minister said the Doha negotiations had concluded, while Qatar said discussions would continue after funeral ceremonies for Khamenei end on July 9.

Technical negotiators focused on implementing the ceasefire framework, sanctions relief and Hormuz arrangements despite lingering regional security tensions.

Technical negotiations continue over shipping, sanctions and ceasefire implementation as mediators work to translate the June accord into practice.

The envoys' presence follows US President Donald Trump's announcement on Monday that Iran had requested a meeting in the Qatari capital — a claim Tehran has denied, saying no direct talks with Washington are planned even as consultations with intermediaries continue.

Trump said US envoys were travelling to Qatar for what he described as a "perhaps important, perhaps not" meeting, adding that Washington hoped to advance efforts towards a permanent agreement.

AFP quoted an American official as saying that the technical talks are slated to continue on all areas of the MOU and both sides will stand down for now and vessels can move freely in and around the Strait of Hormuz.

US Central Command said American fighter jets struck 10 Iranian military sites in and near the Strait of Hormuz, while Islamic Revolutionary Guard Corps said it hit US installations in Bahrain and Kuwait.

Tehran warned of broader retaliation if attacked again as Washington defended its military action, while unrest spread to Beirut after Israel and Lebanon signed a US-brokered framework agreement.

In Israel, Prime Minister Benjamin Netanyahu and Defence Minister Israel Katz said Israeli forces would remain indefinitely in what they described as security zones in southern Lebanon, Syria and Gaza.

He said that technical talks between the United States and Iran are expected to resume in Switzerland on June 29 or 30, as negotiators move to flesh out the details of an agreement that ended months of conflict between the two countries.

Mediators Qatar and Pakistan announced the creation of a direct communication channel designed to reduce the risk of misunderstandings and escalation around the Strait of Hormuz.

Qatar and Pakistan, which mediated the negotiations at a lakeside resort in Switzerland, said in a joint statement that Washington and Tehran had agreed to establish a "de-confliction cell" intended to ensure military operations cease in Lebanon.

US and Iranian negotiators opened talks in Switzerland amid renewed tensions over Lebanon, with both sides linking progress to regional security issues.

The developments came ahead of technical talks between U.S. and Iranian officials expected in Switzerland as both sides seek to implement a fragile accord announced earlier this week aimed at ending the regional conflict.

Lebanon's Health Ministry said at least 21 people were killed and 39 wounded in overnight strikes across southern Lebanon.

"The logistics of these negotiations have never been simple or predictable. As of now the Vice President is not departing tonight," a White House spokesperson said. "We look forward to beginning technical talks as soon as possible."

The accord, signed electronically by both leaders, is intended to serve as a framework for a broader settlement rather than a final agreement, with both sides expected to hold technical talks in the coming weeks.

At the center of the memorandum of understanding is a proposed $300 billion private investment vehicle, known as the Reconstruction and Development Fund, designed to encourage both sides to pursue a final settlement.

Iranian crude exports resumed ahead of a planned US-Iran signing ceremony, even as disputes over Lebanon, shipping rules and implementation remained unresolved.

Questions over shipping fees, sanctions relief and regional security persisted even as negotiators prepared for a formal signing ceremony in Switzerland.

Fresh questions emerged over implementation of the US-Iran agreement as negotiators grappled with security guarantees, territorial disputes and unresolved nuclear issues.

The content of the agreement, which follows weeks of fraught negotiations and periodic threats from Trump of fresh hostilities unless Iran reached a deal, remained unclear.

Mediators voiced growing optimism that weeks of negotiations were nearing completion, while competing narratives from Washington and Tehran underscored lingering disagreements.

Iranian Foreign Minister Abbas Araghchi said the proposed framework would address issues including the U.S. naval blockade and the future administration of the Strait of Hormuz.

Speaking at an Oval Office event, Trump said Washington had achieved a "great settlement" and expressed confidence that an agreement extending the fragile ceasefire established in April could be finalized within days.

Foreign Minister Abbas Araghchi condemned the U.S. attacks and warned that Iran's armed forces would leave "no attack or threat unanswered", while urging foreign militaries to withdraw from the region.

The latest confrontation around the Strait of Hormuz threatens regional shipping security and comes despite renewed diplomatic efforts to stabilize multiple Middle East conflicts.

Both countries, however, warned that they were ready to launch retaliatory attacks if provoked. The renewed hostilities raised concerns that the Middle East could plunge back into a full-scale war.

Air raid alerts sounded across Israel, explosions were reported over Jerusalem, and Iranian state media reported blasts in Tehran, Tabriz and Isfahan.

The U.S. Treasury said the sanctions cover 12 entities, including companies based in the Marshall Islands, the United Arab Emirates and China, as well as several vessels allegedly involved in disguising Iranian LPG shipments as originating from Oman.

Trump also told aides he would not resume all-out war with Iran unless Tehran killed U.S. troops, while U.S. Central Command denied an Iranian claim that it had targeted a U.S. military vessel in the Gulf of Oman.

Iran's Revolutionary Guards Corps, meanwhile, said it had launched missile and drone attacks against the headquarters of the U.S. Fifth Fleet, as well as an airbase and helicopters in a regional country.

The meeting in Washington follows U.S. President Donald Trump's announcement that he had received commitments from both sides aimed at reducing tensions.

Beirut was bracing for a possible Israeli bombardment on Monday after Israel announced plans to strike the city's southern suburbs, raising fears that the fragile cease-fire between Israel and Hezbollah could unravel.

Iran said it fired on a U.S. military base in the region, while the United States reported strikes on Iran’s Bandar Abbas port. Later, Axios reported that Washington and Tehran had agreed on a memorandum of understanding to extend their ceasefire for 60 days.

Iran, which said its proposals presented to Washington included sanctions relief, the release of frozen funds, warned it would “open new fronts” against the United States if attacks resumed.

Pakistan is continuing to play a behind-the-scenes diplomatic role between the United States and Iran as tensions remain high over the ongoing conflict and negotiations.

The incident came hours after India condemned an attack on an Indian-flagged vessel off Oman’s coast, calling continued assaults on commercial shipping “unacceptable”.

The Pentagon on Tuesday revised the estimated cost of the war on Iran to nearly $29 billion, roughly $4 billion higher than the figure presented two weeks ago during Defense Secretary Pete Hegseth’s earlier testimony before Congress.

Shipping disruptions, sanctions and worsening humanitarian fears deepen global anxiety as Washington rejects Tehran’s latest peace proposal over nuclear concessions.

The United States on Friday announced a fresh round of sanctions targeting people and companies in China, Hong Kong, Belarus, and the United Arab Emirates for allegedly helping Iran acquire supplies and military equipment for its missile and drone programs.
