Russia's Foreign Ministry said on Friday that it was "closely monitoring" any military activity on the Korean peninsula, shortly after North Korea officially enshrined the right to use preemptive nuclear strikes, state-owned news agency RIA reported.
RIA quoted the ministry as saying that "recent moves by the US" made it difficult to convince North Korea that its security could be ensured by political, rather than military, means and accused Washington of de-stabilizing the peninsula.
