ABC News Radio cites the Atlantic Council for hosting a Google Hangout discussion with Ukrainian intelligence chief Valentyn Nalyvaichenko:
In a Google Hangout sponsored by the Atlantic Council, security official Valentyn Nalyvaichenko explained there were as many as 30 special troops or officers of Russia’s intelligence service, the GRU, working in the Slaviansk region, plus another 100 in Donetsk.
“They are not alone,” he added, saying that they recruited pro-Russian locals.
The information was provided through three GRU officers detained and questioned by Ukraine, and Nalyvaichenko says they have already identified “two main organizers” responsible for unrest in the region. A criminal investigation has been launched.
