DUBAI: The US wants a peaceful solution to the crisis sparked by attacks on Saudi oil facilities, Secretary of State Mike Pompeo said on Thursday, after Iran raised the prospect of `all-out war`.

Pompeo has blamed Iran for the dramatic weekend assault on two facilities, condemning an `act of war` which knocked out half the kingdom`s oil production.

The rhetoric has raised the risk of an unpredictable escalation in a tinderbox region where SaudiArabia and Iran are locked in a decades-old struggle for dominance.

Af ter meeting allies in Riyadh and Abu Dhabi, Pompeo said there was an `enormous consensus in the region` that Iran carried out the attacks, despite its denials. But he said the US was intent on finding a way out of the confrontation.

`We`d like a peaceful resolution. I think we`ve demonstrated that,` he told reporters. `I hope the Islamic Republic of Iran sees it the same way.

Iran`s Foreign Minister Mohammad Javad Zarif earlier warned any US or Saudi military strike on Iran could cause `all-out war`.

`We don`t want war, we don`t want to engage in a military confrontation,` he told CNN in an interview aired on Thursday.

`But we won`t blink to defendArabia and Iran are locked in a decades-old struggle for dominance.

Pompeo arrived in Abu Dhabi from the Saudi city of Jeddah, where late on Wednesday he met Crown Prince Mohammed bin Salman, the kingdom`s de-facto ruler who has said the assault poses a `real test` of global will.

Saudi officials on Wednesday unveiled what they said were fragments of 25 drones and cruise missiles fired on Saturday at the facilities in the country`s east, engulfing them in flames.

`The attack was launched from the north and unquestionably sponsored by Iran,` defence ministry spokesman Turki alMaliki said, although he refused to be drawn on whether Saudi officials believed Iran directly carried out the operation.

Tehran-linked Houthirebelsin Saudi Arabia`s southern neighbour Yemen have claimed responsibility, but bothWashington and Riyadh have said the operation was beyond the insurgents` capabilities.

French Foreign Minister JeanYves Le Drian also said the Houthi claim `lacks credibility`.

The Houthis have hit dozens of targets in Saudi Arabia, and their rapidly advancing arsenal has exposed the kingdom`s vulnerability despite its vast military spending.

The Houthis said Saturday`s assault was launched from three locations inside Yemen, using advanced drones with long-range capabilities.

They also threatened the United Arab Emirates, a key member of the Saudi-led coalition fighting the Houthis.

Spokesman Brigadier Yahya Saree said the group was ready to attack dozens of targets including the skyscraper-filled cities of Dubai and Abu Dhabi. `If youwant peace and security for your facilities, and towers made of glass that cannot withstand one drone, then leave Yemen alone, he said.

US military planners weighing retaliation have reportedly prepared a list of Iranian targets including the Abadan oil refinery, one of the world`s largest, and Khark Island, the country`s biggest crude export facility, the New York Times said.

Other potentialtargetsinclude missile launch sites and other assets of the elite Islamic Revolutionary Guard Corps, along with bases near the Gulf, where unusual activity suggests they had a role in the strikes.

`Any strikes against Iran would almost certainly be carried out by volleys of cruise missiles from (US) Navy vessels.

Strike aircraft would be aloft to carry out attacks if Iranian retali-ated against the first wave,` the newspaper said.

Cinzia Bianco, a Middle East analyst at the European Council on Foreign Relations, warned of `an out-of-control chain of escalatory events`. `Inside Saudi Arabia, there is uncertainty over the most appropriate course of action,` she said.

`However the dominant thinking there points to the US targeting critical infrastructure in Iran as to minimise or exclude any humancost.`Late onWednesday, CBS News cited an unnamed US official as saying Iran`s supreme leader Ayatollah Ali Khamenei had approved the attack,on condition it be carried out in a way that would allow Iran to deny involvement.

US officials it quoted said unreleased satellite photos showed Iran`s Revolutionary Guard Corps making prepara-tions for the attack at Ahvaz airbase. But the commander of Iran`s Revolutionary Guards, Major General Hossein Salami, said on Thursday his country was `so powerful that they are forced to falsely accuse us` of being behind any incident.

An international inquiry is under way, with the United Nations saying on Thursday experts had arrived in the kingdom and begun their mission `at the invitation of the Saudi authorities`.

Trump, who has already reimposed sanctions that have cripple d Ir an`s economy, promise d on Wednesday to `substantially increase` the measures, winning quick praise from Riyadh.

Zarif, himself under US sanctions since July 31, described the measures as `illegal` and `inhuman` and designed to hurt ordinary citizens.-AFP
