This was stated by spokesman of the National Security and Defense Council Volodymyr Chepovyi at a briefing on Monday, Ukrainska Pravda reports.
"The militant leaders declare that they have no intent to lay down arms and seek to pass the responsibility for the failure of the truce on the Ukrainian side through organizing sabotage," he said.
He also stated that the terrorists are trying to restore human reserves by forcibly enlisting local people and citizens of Russia.
"In the nearest future the mercenaries from training camps in the territory of Russia are scheduled to make a breakthrough into the territory of Ukraine," Chepovyi said.
According to the secretary of the NSDC they are going to supply the militants with human resources and weapons.
Mercenaries are being hired in Russia via social networks.
"They search for volunteers to send them in the East of Ukraine through Russian social media," Chepovyi said.
"All fighters, terrorists, and saboteurs who violate the ceasefire will be responded adequately and in a rough way," he added.
