KSA Says Oil Tanker Bombed in 'Terrorist Attack'

A blast rocked a Singapore-flagged oil tanker at the Saudi port of Jeddah Monday, the vessel's owner said, with the kingdom saying it was struck by an explosives-laden boat in a "terrorist" assault.

All 22 sailors aboard the tanker BW Rhine escaped unhurt after the blast struck just after midnight, Singapore-based shipping company Hafnia said, but it did not exclude the possibility of an oil spill.

No group has so far claimed responsibility for what marks the latest in a string of attacks on Saudi energy sector targets, but it comes as Iran-backed Huthi rebels in neighboring Yemen step up cross-border strikes against Saudi Arabia. 

"BW Rhine has been hit from an external source whilst discharging at Jeddah... causing an explosion and subsequent fire onboard," Hafnia said in a statement.

"The crew have extinguished the fire with assistance from the shore fire brigade and tug boats," it added.

The vessel was "attacked by an explosive-laden boat", the official Saudi Press Agency (SPA) reported, citing an energy ministry spokesman who condemned the "terrorist" attack.

"The incident did not result in any casualties, and there was no damage caused to the unloading facilities, nor any effect on supplies," SPA said, without specifying who was behind the assault.

"These acts of terrorism and vandalism, directed against vital installations, go beyond the kingdom and its vital facilities, to the security and stability of energy supplies to the world and the global economy."

Jeddah, the second biggest Saudi city, is home to a key Red Sea port and distribution center for oil giant Saudi Aramco.

Hafnia reported "hull damage" in the blast.

"It is possible that some oil has escaped from the vessel, but this has not been confirmed and instrumentation currently indicates that oil levels on board are at the same level as before the incident," it said.

Dryad Global, a London-based maritime intelligence firm, also reported the explosion, saying it struck a vessel while "carrying out operations within the main tanker anchorage at the Saudi Aramco Jeddah port".

The United Kingdom Maritime Trade Operations (UKMTO) said it was aware of an explosion and warned vessels in the area to exercise "extreme caution".

- Series of attacks -

The incident comes after an explosion last month rocked a Greek-operated oil tanker docked at the southern Saudi port of Shuqaiq, an attack that a Riyadh-led military coalition blamed on Yemen's Huthi rebels.

No injuries were reported in that blast on the Maltese-flagged Agrari tanker, according to its Greece-based operator TMS Tankers, while Dryad Global said it was caused by a "water-borne improvised explosive device" launched by the Huthis.

Just days earlier, the Huthi rebels said they struck a plant operated by Aramco in Jeddah with a Quds-2 missile. Aramco said that strike tore a hole in an oil tank, triggering an explosion and fire.

The incidents, which underscore the Huthis' advancing arsenal and the vulnerability of Saudi Arabia's oil infrastructure, come as the rebels escalate attacks on the kingdom in retaliation for a five-year military campaign led by Riyadh.

Saudi Arabia has been targeted with dozens of ballistic missile and drone attacks since the start of last year, many of which the kingdom claims to have successfully intercepted.

The oil powerhouse is stuck in a military quagmire in Yemen, which has been locked in conflict since the rebels took control of the capital Sanaa in 2014 and went on to seize much of the north.

Riyadh led a coalition that intervened to support the internationally recognized government the following year, but the conflict has shown no real signs of abating since.

Saudi Arabia has repeatedly accused regional rival Iran of supplying sophisticated weapons to the Huthis, a charge Tehran denies.

Tens of thousands of people, mostly civilians, have been killed and millions displaced in Yemen's war, which the United Nations has called the world's worst humanitarian disaster.
