The South Korean labor ministry has ordered the closure of two nuclear reactors under construction, after a toxic gas leak killed three workers. The incident comes in the wake of cyberattacks and threats against the reactor’s operator, RT reported.

“We will promptly conduct an investigation and hold accountable those who are responsible (in the incident) if any irregularities are discovered,” the head of the Ulsan branch of labor ministry, Yoo Han-bong, said on Saturday, according to South Korea’s Yonhap news agency. Korea Hydro and Nuclear Power Co., which runs the site where the incident happened, says it suspects the deaths were caused by a leak of nitrogen gas from an underground cable.

The two shut down reactors are New Gori No. 3 (99 percent complete and awaiting commission in June) and New Gori No. 4 (98 percent complete and expected to become operational in 2016), about 400 kilometers southeast of Seoul. The accident comes as the state-run Korea Hydro and Nuclear Power Co. (KHNP), operating the facilities, stays on high alert, following a cyberattack on its computer system and threats of “destruction” by hackers, claiming they can access KHNP’s control systems.
