Iran leader rules out US talks amid tensions over Saudi attacks
Iran's supreme leader on Tuesday ruled out negotiations with the US "at any level", as tensions mounted between the arch-foes after Washington blamed Tehran for attacks on Saudi oil installations.
Ayatollah Ali Khamenei said the US adopted a policy of "maximum pressure" on Iran because it believes it cannot bring the Islamic Republic to its knees through other means.
The leader was speaking after devastating drone attacks at the weekend that halved oil output of Iran's regional arch-rival Saudi Arabia - the world's top crude exporter.
"The policy of 'maximum pressure' against the Iranian nation is worthless and all Islamic Republic of Iran officials unanimously believe there will be no negotiations with the US at any level," he said in a televised address.
Tensions between Iran and the US and its allies have threatened to boil over since May last year when President Donald Trump abandoned a 2015 nuclear deal and began reimposing sanctions in its campaign of "maximum pressure".
Iran singled out
Trump said the US was ready to help Saudi Arabia after the attacks that halted about six percent of the world's oil supply and triggered a record leap in crude prices.
"I'm not looking to get into new conflict, but sometimes you have to," he said. "That was a very large attack, and it could be met by an attack many, many times larger.
"Certainly, it would look to most like it was Iran," Trump added.
US Secretary of Defence Mark Esper also singled out Iran as a regional destabilising force, while stopping short of directly accusing Tehran over the strikes.
The US military, he said, was working with its partners to "address this unprecedented attack and defend the international rules-based order that is being undermined by Iran".
A day after the attacks, the White House had said Trump could meet his Iranian counterpart Hassan Rouhani on the sidelines of the UN General Assembly in New York next week.
Rouhani has already rejected the possibility of direct negotiations with the US unless it lifts all sanctions.
The Iranian president has said even if the sanctions are lifted, any talks must be held in the framework of the nuclear accord.
US must 'repent'
Khamenei reiterated this on Tuesday, saying that if the US "repents" and returns to the Joint Comprehensive Plan of Action, then it can talk with Iran along with other parties to the deal.
"If the US takes back its words and repents after pulling out of the JCPOA... then it can join the other countries party to the JCPOA and talk to Iran along with the other countries," he said, using the deal's formal title.
"Without this, no negotiations will happen at any level between the Islamic Republic of Iran's officials and the Americans, not during the visit to New York or any other visit."
Yemen's Iran-aligned Houthi rebels claimed responsibility for Saturday's attacks on Abqaiq - the world's largest oil processing facility - and the Khurais oil field in eastern Saudi Arabia.
The Houthis said ten drones struck the sites, but Saudi Arabia pointed the finger of blame at Iran.
"All indications are that weapons used in both attacks came from Iran" rather than Yemen, said Turki al-Maliki, spokesman for a Saudi-led military coalition.
Rouhani said the attacks were an act of self-defence by the Houthis against the coalition that has been bombing them since 2015 in support of Yemen's internationally recognised government.
As the aftershocks of the attacks continued to ripple across financial markets on Tuesday, energy specialists S&P Platt said around three million barrels per day of Saudi crude would remain offline for at least a month.
China condemned the attacks and appealed to all sides to "refrain from taking actions that lead to an escalation of tensions in the region".
