Two Russian LifeNews journalists, Oleg Sidyakin and Marat Saichenko, were captured on Sunday by Ukrainian troops presumably near Kramatorsk, a town in the Donetsk Region, the residents of which voted for independence from Kiev in a May 11 referendum.

On Monday, the deputy secretary of Ukraine’s National Security and Defense Council (SNBO) said the journalists were being investigated on the charges of “aiding the terrorist groups.”
