"In the east of Ukraine, the Russian army is being activated," the NSDC press service quoted Turchynov as saying on Tuesday.According to the reports, Russia's engineering detachments have built five pontoon ferries over the Siversky Donets river on the Ukrainian-Russian border, as well as building access routes to the ferries. "Thus, military infrastructure is being formed to ensure redeployment of additional detachments of Russian troops to the occupied territory of Ukraine to use them in battle," Turchynov said, adding that this is more evidence of the direct involvement of the Russian military in the conflict in eastern Ukraine.
