Russia confirms 5 killed in rocket explosion, as experts believe it involved a nuclear-powered missile
- A nearby city experienced a spike in radiation levels, but Russia’s military has denied this
- US experts believe Russia was working on nuclear propulsion for a cruise missile
Russia’s nuclear agency on Saturday said an explosion at an Arctic missile testing site had killed five of its staff, after the military had put the toll at two.
The accident happened during the testing of a liquid propellant rocket engine at a missile test site in the far northern Arkhangelsk region on Thursday.
US-based nuclear experts said on Friday they suspected it involved a nuclear-powered cruise missile vaunted by President Vladimir Putin last year.
Russia calls the missile the 9M730 Buresvestnik. The Nato alliance has designated it the SSC-X-9 Skyfall.
In a statement, Rosatom said the accident killed five of its staff and injured three others, who suffered burns and other injuries.
The statement came after authorities in a nearby city said the accident had caused a spike in radiation levels, which was denied by the military.
Rosatom said its staff were providing engineering and technical support for the “isotope power source” of the missile engine.
The authorities have released few details of the accident at the Nyonoksa test site on the White Sea, used for testing missiles used in nuclear submarines and ships since the Soviet era.
