At least 14 people were killed Sunday in a civilian helicopter crash in Saudi Arabia, the international news network Reuters reported. The damaged aircraft belonged to the state-owned energy and oil giant Saudi Aramco.

The crash occurred in the Ras Tanura area in the country’s east—a strategic region that houses one of the company’s largest oil export terminals and refining facilities in the world. The impact killed at least 14 people aboard the helicopter, and local emergency crews were called to the scene.

The circumstances of the crash and what caused the aircraft to go down remain unclear. Saudi authorities are keeping a low profile, and so far neither the government in Riyadh nor Saudi Aramco management has issued any official statement regarding the exact number of casualties or their identities.
