The aircraft went down at approximately 6:00 a.m. local time. Officials confirmed that everyone on board was killed. The identities of the victims have not yet been released publicly.

Saudi authorities have launched a formal investigation to determine the cause of the accident. At this stage, no information has been provided regarding the circumstances surrounding the crash, and officials have urged against speculation while investigators examine the evidence.

The Ministry of Energy extended its condolences to the families of those who lost their lives and said relevant agencies are working together to establish the facts surrounding the incident.
