At least five people were killed and two others injured after an explosion followed by a fire broke out at a defense company facility in South Korea on Monday.
The incident occurred at a worksite operated by Hanwha Aerospace in the city of Daejeon, one of the company’s key facilities involved in the development of large-scale propellants and surface-to-surface weapons systems.
Authorities said the cause of the explosion was not immediately known and an investigation was underway.
Emergency official Yoon Seong-su said the site is designated as a government security facility.
Medical official Kim Ju-yeon said one of the two injured victims was in critical condition. The identities of those killed had not yet been confirmed.
Hanwha Aerospace is a major South Korean defense manufacturer, and the Daejeon facility plays a significant role in the country’s weapons development programs.
