Iran’s parliament speaker has said the Strait of Hormuz will remain closed until the US fulfils commitments under a June agreement and meets Tehran’s conditions.

Mohammad Bagher Ghalibaf said Iran had “explicitly conveyed its conditions to the opposing side through intermediaries,” state broadcaster IRIB reported.

He said “the path of deception and unilateral imposition is closed,” adding that until Iran’s rights are recognised and US commitments fulfilled, there will be no return to previous negotiations or reopening of the Strait of Hormuz.

US President Donald Trump cut short a weekend at Camp David to return unexpectedly to the White House on Saturday, as tensions rose in the Middle East.

The change in plans came as the Saudi-led coalition fighting Yemen's Houthis said on Saturday that the group fired a ballistic missile at Riyadh at dawn, after a fire broke out near the Saudi capital's international airport.

Jordan and Bahrain have condemned the latest Houthi attacks targeting Saudi Arabia, expressing solidarity with Riyadh and warning that attacks on civilians and civilian infrastructure violate international law.

Jordanian Foreign Ministry spokesman Fouad Al-Majali said Amman had "absolute" solidarity with Saudi Arabia and supported all measures taken to protect its sovereignty, security, stability and citizens.

Bahrain similarly condemned what it called an escalation in Iranian-backed Houthi attacks. The Foreign Ministry described the attacks as a "blatant violation of international law, international humanitarian law, the UN Charter and relevant UN Security Council resolutions."

UN Secretary-General Antonio Guterres and Gulf Cooperation Council (GCC) head Jasem Mohamed Albudaiwi strongly condemned Houthi attacks on Saudi Arabia, warning that the group's targeting of civilian objects poses a severe threat to regional peace and security.

Guterres received Albudaiwi in New York on the sidelines of the GCC chief's participation in the 81st session of the UN General Assembly, according to a statement from the GCC Secretariat General.

"Both officials strongly condemned the Houthi militia's attacks against the Kingdom of Saudi Arabia and their deliberate targeting of civilian objects, underscoring the severe threat these hostile actions pose to regional peace and security," it said.

Foreign Minister Afrah al-Zouba has said that Yemen is not an "Iranian bargaining chip" or an arena for settling regional scores, describing the country's partnership with Saudi Arabia as "firm."

Her remarks came in an interview published by Yemen's official Saba news agency as government forces and Iran-allied Houthis continued fighting on several fronts in the country.

"Restoring Yemeni state institutions is a pillar of Yemen's security, regional stability and the safety of maritime routes, and the government is dealing with the repercussions of recent developments responsibly and with commitment," said al-Zouba.

Iran has called on the US to abide by the framework deal the countries reached this June, saying the Pakistani-brokered pact represents a sovereign decision approved by the country’s highest leadership.

Interior ministry spokesperson Ali Zainvand made the remarks while commenting on a possible visit to Tehran by Pakistan’s Interior Minister Mohsin Naqvi, according to Iranian state TV.

“A large number of countries are making efforts to resolve this issue and bring the parties back to the point of understanding,” said Zainvand.

He said Pakistan’s mediation role and other diplomatic initiatives are continuing strenuously.

“International diplomatic efforts and mediation are still underway to resolve the problems and return to the Islamabad Memorandum of Understanding,” he added, using the deal’s official name.

“The other side must respect the value of its signature and adhere to the provisions of the agreement. The US must abide by the terms of the Islamabad agreement,” he said.

Yemen's Houthis have said that they launched strikes targeting "sensitive sites" in Saudi Arabia's Riyadh and oil facilities in the kingdom's port city of Yanbu, hours after residents reported blasts in the Saudi capital.

"In response to the Saudi attempts to target the capital Sanaa, the Yemeni Armed Forces carried out two successful military operations using a large number of ballistic and cruise missiles and drones," Houthi military spokesperson Yahya Saree said in a statement on Telegram.

"The first targeted sensitive sites in the Saudi capital, Riyadh, and the second targeted Aramco facilities in Yanbu."

“CENTCOM forces have supported more than 1 billion barrels of crude oil leaving the Gulf,” Brad Cooper said in remarks released by the command on X.

Cooper said US forces have also assisted more than 2,000 commercial vessel transits through the strategic waterway by providing coordinated protection.

He said the primary transit lanes in the strait have been cleared of mines and that thousands of ships have passed through the waterway.

At the same time, Cooper said Iran had exported “zero barrels” of oil, attributing the halt to what he called the US “ironclad blockade.”
