Two contract workers have been killed at an oil refinery in Saudi Arabia.
Another two contractors were injured at the SASREF plant in Jubail in the incident on Sunday, the company said.
“SASREF immediately activated response teams to identify the source of the incident and responded to the situation,” the statement said.
“The safety of our people and operations is a top priority.”
The company, which is owned by Saudi Aramco, said additional safety measures would be put in place to prevent incidents in the future.
The 305,000 barrel per day SASREF refinery had until September been a joint venture between Aramco and Royal Dutch Shell.
Aramco bought it as part of a strategy to expand its downstream operations.
