Dubai:The US wants a peaceful solution to the crisis sparked by attacks on Saudi oil facilities, Secretary of State Mike Pompeo has said, 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 Saudi Arabia and Iran are locked in a decades-old struggle for dominance.
After meeting with 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 and Yemeni rebels' claims that they were responsible.
But Pompeo 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 on Thursday.
"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," he told CNN in an interview aired Thursday, "but we won't blink to defend our territory."
Saudi officials on Wednesday unveiled what they said were fragments of 25 drones and cruise missiles fired Saturday at the oil 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 al-Maliki said, although he refused to be drawn on whether Saudi officials believed Iran directly carried out the operation.
Tehran-linked Huthi rebels in Saudi Arabia's southern neighbour Yemen have claimed responsibility, but both Washington and Riyadh have said the operation was beyond the Yemeni insurgents' capabilities.
French Foreign Minister Jean-Yves Le Drian also said the Huthi claim "lacks credibility".
The Huthis have however hit dozens of targets in Saudi Arabia, and their rapidly advancing arsenal has exposed the kingdom's vulnerability despite its vast military spending.
The Huthis 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 Shiite rebels -- with strikes against "towers made of glass that cannot withstand one drone", in apparent reference to the glitzy cities of Dubai and Abu Dhabi.
