On Tuesday, Russian President Vladimir Putin said that a Ukrainian sabotage group, which sought to blow up power lines in Russia and was captured, admitted that they were trained by instructors from the United Kingdom.
"Yes, indeed, [Russia] will [deliver a demarche], as we did previously and continuously, and conveyed to London both through open channels, making it public, and through diplomatic channels, the inadmissibility of participating in such activities," Zakharova said on the sidelines of the Eastern Economic Forum (EEF) in Vladivostok.
