Russia’s nuclear agency said Saturday that five of its employees were killed earlier this week when a rocket engine exploded during a missile test at a military base in the far northern Arkhangelsk region.
Russia’s Defense Ministry initially said that said two people died in Thursday’s explosion and four were injured, including servicemen and civilian engineers. It was not immediately clear if the five fatalities cited in a Saturday statement by Rosatom were all in addition to the previously reported deaths.
In addition to the five deaths, Rosatom said three of its employees were treated for burns. The test took place on a sea platform during a period of work related to the engineering and technical support of “isotopic power sources” in a “liquid propulsion system,” the agency said.
