Saudi Arabia said armed drones had struck two oil pumping stations in the kingdom on Tuesday in what it called a “cowardly” act of terrorism two days after Saudi oil tankers were sabotaged off the coast of the United Arab Emirates.
The energy minister of the world’s largest oil exporter said the attack caused a fire, now contained, and minor damage at one pump station, but did not disrupt oil production or exports of crude and petroleum products.
Oil prices spiked on news of the attack on the stations, more than 320km west of the capital Riyadh. Brent crude futures then rose 1.38 percent to trade at US$71.20 (RM296.94).
Energy Minister Khalid al-Falih, in comments run by state media, said the drone attack and Sunday’s sabotage of four vessels, including two Saudi tankers, off Fujairah emirate, a major bunkering hub, threatened global oil supplies.
“These attacks prove again that it is important for us to face terrorist entities, including the Houthi militias in Yemen that are backed by Iran,” Falih said in an English-language statement issued by his ministry.
Houthi-run Masirah TV earlier said the group had launched drone attacks on “vital” Saudi installations in response to “continued aggression and blockade” on Yemen.
A Saudi-led coalition has been battling the Houthis for four years in Yemen to try to restore the internationally recognised government, in a conflict widely seen as a proxy war between Saudi Arabia and Iran.
The Houthis have repeatedly launched drone and missile attacks on Saudi cities, but two Saudi sources told Reuters this was the first time an Aramco facility was hit by drones.
State-run Aramco said it had temporarily shut down the East-West pipeline, known as Petroline, to evaluate its condition. The pipeline mainly transports crude from the kingdom’s eastern fields to Yanbu port, which lies north of Bab al-Mandeb.
The attacks occur amid a war of words between Washington and Tehran over sanctions and US military presence in the region.
The Saudi stock index, which suffered two days of heavy losses, opened 1.5 percent higher but was trading down 0.3 percent. A Saudi-based banker told Reuters that state funds were supporting local stocks to limit the downside.
Iran in focus
The UAE has not revealed details about the nature of the attack on ships near Fujairah port, which lies just outside the Strait of Hormuz, or blamed any party or country.
Iran was a prime suspect in the sabotage on Sunday although Washington had no conclusive proof, a US official familiar with American intelligence said on Monday.
Iran has denied involvement and described the attack on the four commercial vessels as “worrisome and dreadful”. It has called for an investigation.
The US ambassador to Saudi Arabia said Washington should take what he called “reasonable responses short of war” after it had determined who was behind the attacks near Fujairah.
“We need to do a thorough investigation to understand what happened, why it happened, and then come up with reasonable responses short of war,” Ambassador John Abizaid told reporters in the Saudi capital Riyadh in remarks published on Tuesday.
“It’s not in (Iran’s) interest, it’s not in our interest, it’s not in Saudi Arabia’s interest to have a conflict.”
The US embassy in the UAE advised its citizens to maintain a high level of vigilance on heightened tensions in the region.
Washington has increased sanctions on Tehran, saying it wants to reduce Iranian oil exports to zero, after quitting the 2015 nuclear pact between Iran and global powers last year.
The US Maritime Administration said last week that Iran could target US commercial ships including oil tankers sailing through Middle East waterways. Tehran has called the US military presence “a target” rather than a threat.
A fifth of global oil consumption passes through the Strait of Hormuz from Middle East crude producers to markets in Asia, Europe, North America and beyond. The narrow waterway separates Iran from the Arabian Peninsula.
Iran’s Revolutionary Guards threatened last month to close the chokepoint if Tehran was barred from using it.
US President Donald Trump wants to force Tehran to agree a broader arms control accord and has sent an aircraft carrier and B-52 bombers to the Gulf in a show of force against what U.S. officials have said are threats to US troops in the region.
