Iranian Supreme Leader Ayatollah Ali Khamenei ruled out talks with the United States unless the Trump administration returns to the nuclear accord between Iran and the West that the United States abandoned past year. "That was an attack on Saudi Arabia, and that wasn't an attack on us". "They've got to change behavior if we're going to have conversations because right now, the situation is untenable".
Prince Abdulaziz said production capacity would be up to 11 million barrels per day by the end of September.
The US, later on, claimed that Iran was behind the attack, which was follow-on supported by news reports showing the attacks were conducted through Iranian measures.
US President Donald Trump remains open to meeting with Iranian President Hassan Rouhani, but Khamenei said that Iran would not hold talks with the US in NY or "any other place", unless Washington returns to the 2015 nuclear deal that it unilaterally pulled out of a year ago.
Trump, alternating between aggressive and nonviolent reactions, said the USA could respond "with an attack many, many times larger" but also "I'm not looking at options right now".
Aramco, the Saudi oil company targeted, said no workers were injured in the attack.
Diplomatic efforts by French President Emmanuel Macron had raised hopes that Trump and Iranian President Hassan Rouhani might at the upcoming United Nations General Assembly in NY, but the operation against the Saudis seems to have torpedoed the proposal.
USA officials say Trump wants to ensure the culprit is positively identified in a way that will pass muster not only with him but with the American people.
Gidley said President Trump is "being cautious" in his assessment.
Trump declared Monday it "looks" like Iran was behind the explosive attack on the Saudi oil facilities.
For months, Iranian officials have issued veiled threats, saying that if Tehran is blocked from exporting oil, other countries will not be able to do so either.
Yemen's Iranian-backed Houthi rebels have claimed responsibility for the attacks, and Iran has denied involvement.
Riyadh asked worldwide experts to join its investigation, which indicates the attack did not come from Yemen, the foreign ministry said.
"The US regime seeks to set it as a definite policy for both its internal rivals and for the Europeans that the only way to deal with Iran would be maximum pressure", Ayatollah Khamenei said, adding that Washington is looking for a way to allege that the policy of maximum pressure is effective and the Iranian officials have to go to the negotiating table.
The attacks cut 5 per cent of world crude oil production and caused oil prices to surge by as much as 19 per cent. USA oil was down 5.4% to $59.50.
"US intelligence services have the capability of determining where the missiles were launched from, the official said, declining, however, to say how many were fired".
The Trump administration should not offer Iran any opportunities to negotiate after this weekend's assault on Saudi Arabia's oil installations, which was launched from Iranian soil, Fox News senior strategic analyst Gen. Jack Keane argued on Monday.
Ayatollah Khamenei cautioned everyone about the U.S.'s intention from proposing negotiations with Iran again and held: Everyone should know and notice that this is a trick.
Russian Federation and China said it was wrong to jump to conclusions about who was to blame for the attack on Saudi Arabia.
"If America takes back its words and repents and returns to the nuclear deal, which they have violated, they can take part in the meetings of signatories to this agreement with Iran", Khamenei told reporters, according to the Mehr news agency. The security council meets next week in NY.
