An attack on Saudi Arabia that triggered the biggest jump in oil prices in almost 30 years was carried out with Iranian weapons, a Saudi-led coalition said on Monday, as President Donald Trump said the United States was "locked and loaded" to hit back. The Iran-aligned Houthi group that controls Yemen's capital claimed responsibility for Saturday's attack, which knocked out more than half of Saudi Arabia's oil production and damaged the world's biggest crude processing plant.
Iran denied U.S. accusations it was to blame and said it was ready for "full-fledged war". Two sources briefed on state oil company Saudi Aramco's operations told Reuters it might take months for Saudi oil production to return to normal. Earlier estimates had suggested it could take weeks.
A Saudi-led military alliance battling the Houthis said the attack on Saudi oil plants was done with Iranian weapons and was not launched from Yemen, according to preliminary findings. Coalition spokesman Colonel Turki al-Malki said that an investigation into Saturday's strikes, which shut 5% of world crude output, was going on to determine the launch location.
"The preliminary results show that the weapons are Iranian and we are currently working to determine the location ... The terrorist attack did not originate from Yemen as the Houthi militia claimed," Malki told a news conference in Riyadh. U.N. Yemen envoy Martin Griffiths told the Security Council on Monday it was "not entirely clear" who was behind the strike but he said it had increased the chances of a regional conflict.
But U.S. Ambassador to the world body, Kelly Craft, told the Council that emerging information on the attacks "indicates that responsibility lies with Iran" and that there is no evidence the attack came from Yemen.
Iran rejected U.S. accusations that it was responsible. "These allegations are condemned as unacceptable and entirely baseless," Foreign Ministry spokesman Abbas Mousavi said in remarks carried by state TV.
Oil prices surged by as much as 19% before coming off their peaks. The intraday jump was the biggest since the 1990-91 Gulf crisis over Iraq's invasion of Kuwait. The market eased from its peak after Trump announced that he would release U.S. emergency supplies and producers said there were enough stocks stored up worldwide to make up for the shortfall. Prices were around 12% higher by 1645 GMT.
The kingdom said it would be able to meet customers' demand from its ample storage, although some deliveries had been disrupted. At least 11 supertankers were waiting to load oil cargoes from Saudi ports, ship tracking data showed on Monday. Traders spoke of a long-term price increase as markets absorb the proof that global supply can hit so hard in a single strike.
"LOCKED AND LOADED"
Trump said the United States was "locked and loaded" to respond to the incident.
"There is reason to believe that we know the culprit, are locked and loaded depending on verification, but are waiting to hear from the Kingdom as to who they believe was the cause of this attack, and under what terms we would proceed!" Trump said on Twitter on Sunday. U.S. Energy Secretary Rick Perry pinned the blame squarely on Iran for "an attack on the global economy and the global energy market".
"The United States wholeheartedly condemns Iran's attack on Saudi Arabia and we call on other nations to do the same," he said in a speech to an annual meeting in Vienna of the U.N. nuclear watchdog IAEA. He added that he was confident the oil market "is resilient and will respond positively". While Iran has denied blame for the attacks, its Yemeni allies have promised more strikes to come. Houthi military spokesman Yahya Sarea said the group carried out Saturday's pre-dawn attack with drones, including some powered by jet engines.
"We assure the Saudi regime that our long arm can reach any place we choose and at the time of our choosing," Sarea tweeted. "We warn companies and foreigners against being near the plants that we struck because they are still in our sights and could be hit at any moment." U.S. officials say they believe that the attacks came from the opposite direction, possibly from Iran itself rather than Yemen, and may have involved cruise missiles. Wherever the attacks were launched, however, they believe Iran is to blame.
"There's no doubt that Iran is responsible for this. No matter how you slice it, there's no escaping it. There's no other candidate," a U.S. official said on Sunday. Saudi Arabia and Iran have been enemies for decades and are fighting a number of proxy wars, including in Yemen where Saudi forces have been fighting against the Houthis for four years.
Tension in the oil-producing Gulf region has dramatically escalated this year after Trump imposed severe U.S. sanctions on Iran aimed at halting its oil exports altogether.
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. However, Iran has denied a role in specific attacks, including bombings of tankers in the Gulf and previous strikes claimed by the Houthis.
Russia and China said it was wrong to jump to conclusions about who was to blame for the attack on Saudi Arabia. Britain - a close ally of Washington but wary nevertheless of its hardline Iran policy - stopped short of ascribing blame but described the assault as a "wanton violation of international law".
Washington has imposed its "maximum pressure" strategy on Iran since last year when Trump quit an international deal that gave Tehran access to world trade in return for nuclear curbs. U.S. allies in Europe oppose Trump's strategy, arguing that it provides no clear mechanism to defuse tensions, creating a risk that the foes could stumble into war.
Trump has said his goal is to force Iran to negotiate a tougher agreement and has left open the possibility of talks with President Hassan Rouhani at an upcoming U.N. meeting. Iran says there can be no talks until Washington lifts sanctions. Its foreign ministry said on Monday Rouhani would not meet Trump. Officials in big energy-exporting countries were eager to assert that global markets could cope with the Saudi outage.
Saudi Arabia is not only the world's biggest oil exporter; it also has a unique role in the market as the only country with enough spare capacity to increase or decrease its output by millions of barrels per day, keeping the market stable.
