Saudi Arabian security forces killed a suspected attacker in a security facility in Saudi Arabian eastern province of Abqaiq, state television reported on Friday.
Abqaiq is one of the largest oil-producing Provinces in the Kingdom’s east.
Saudi news channel Al Ikhbariya TV said “there was no 'terrorist organisations' in Abqaiq but a single terrorist, eventually surrounded and killed after attacking a security officer."
No more information was given out by the channel.
It could not be immediately confirmed if the Abqaiq attack was near any key energy facilities. Reuters could not reach Saudi security and oil officials to comment.
Saudi Arabia is the world's biggest oil exporter and strategic ally of the United States.
The Saudi Interior Ministry had released a statement in April, in which residents were warned of possible attacks on vital spots like shopping malls and energy installations, security forces were put on perpetual high alert as well.
Four al Qaeda militants had once breached the gates of Saudi Aramco's Abqaiq plant in 2006, but did not manage to cause damage and was soon shot on the spot by security guards, Saudi authorities said.
Saudi Arabian authorities have announced that six different possible attacks have been thwarted during July alone, in addition to hundreds of suspects being arrested for belonging to the ISIS militant group. 431 people have been arrested in suspicion of belonging to ISIS.
Riyadh has been leading air strikes against Iranian backed Houthi militias in neighbouring Yemen since March 26.
The war in Yemen started when Houthi aggression pushed the Yemeni president Abd Rabbuh Mansour Hadi to call on Arab countries to “help save Yemen”. And so King Salman of Saudi Arabia has responded to the call and the military operations started in late March of this year. The Saudi-led ‘decisive storm’ operations, in which the Kingdom joined forces with 12 other countries to aid the exiled Yemeni government.
The UN has declared the situation in Yemen to be a level-three humanitarian emergency, the highest on its scale, after about 80 percent of the country’s population fell into dire need of humanitarian aid.
