Washington Times cites the Atlantic Council for hosting a Google Hangout discussion with Ukrainian intelligence chief Valentyn Nalyvaichenko:
Russian military officers are the “main provocateurs and main organizers” of the unrest, Mr. Nalyvaichenko said in a Web briefing organized by the Atlantic Council. “We, for sure, know who they are. [The Russian officers] are very dangerous, well-armed, for years before prepared to do what they are doing now,” he said.
Mr. Nalyvaichenko said Ukrainian authorities have detained 21 members of the Russian military intelligence service network, including three GRU officers who are being held in Kiev. Up to 30 Russian GRU officers are working in the Slovyansk district and “hundreds and hundreds” of their agents are behind the unrest in eastern Ukraine, he said.
