Russia’s nuclear agency chief on Monday confirmed that 5 scientists killed last week were developing “new weapons,” and vowed to continue testing despite the explosion.
The accident took place at an Arctic military facility on the coast of the White Sea on Thursday, but Russian authorities only admitted its nuclear nature on Saturday.
US experts have said it could be linked to the testing of the "Burevestnik" cruise missile, touted by President Vladimir Putin earlier this year. National nuclear agency Rosatom on Monday honoured the memory of its five dead scientists.
"The best (thing) for their memory will be our further work on the new weapons," the head of Rosatom Alexei Likhachev was quoted as saying by agencies.
"We are fulfilling the task of the motherland, its security will be reliably ensured," he added.
