Fourteen people were killed when a helicopter belonging to Saudi oil giant Aramco crashed in Ras Tanura, on the kingdom's eastern Gulf coast, Sunday, the Saudi Press Agency (SPA) reported, adding that all those onboard died and the cause of the crash remained unknown.
An official source at the energy ministry said the aircraft came down at 6am local time. "The accident claimed the lives of all 14 passengers, all Saudi citizens," SPA said.
"The relevant authorities have launched a full investigation to determine the cause of the crash," the agency added.
The ministry offered its condolences to the bereaved families. "The energy ministry extends its deepest condolences and sincere sympathies to the families of the victims, praying that Almighty Allah grants them mercy and forgiveness and accepts them among the martyrs," SPA said.
Aramco operates more than 60 aircraft, including helicopters serving over 300 heliports across Saudi Arabia — one of the largest corporate fleets in the region. The company did not respond immediately to an emailed request for comment.
Ras Tanura is home to one of the largest refineries in the Middle East, with a capacity of 550,000 barrels per day (bpd), and is critical to the kingdom's energy sector. Aramco resumed crude oil loadings at its Ras Tanura terminal on Friday, after they had been halted for nearly four months.
The crash comes as oil-rich Gulf states race to move cargoes and ramp up output following Iranian attacks and the closure of the Strait of Hormuz, a vital waterway for oil and gas exports, ahead of an interim deal to halt the war between the US and Iran.
Riyadh gave no indication that the incident was connected to any hostile attack. During the conflict, Iranian strikes had targeted energy facilities across the Gulf, and the Ras Tanura refinery was hit several times — notably by a drone attack at the start of the war that caused a fire and forced a partial shutdown. Riyadh said in April that the weeks-long assault had disrupted operations at key facilities, including refineries at Ras Tanura, Jubail, Yanbu and Riyadh.
Saudi Arabia, the world's leading crude exporter, produces a little over 10mn bpd.
