MOSCOW, April 10. /TASS/. Ukrainian sabotage groups are stepping up their activity in the Donetsk People’s Republic, interim head of the Donetsk People’s Republic Denis Pushilin said on Monday.

"Indeed, we are now seeing the enemy stepping up its activity in the form of missions by sabotage groups. As a matter of fact, this tactic of the enemy isn’t new. They, as part of their terrorist activity, killed the first DPR head, Alexander Zakharchenko, and a number of heroic commanders: Motorola (Arseny Pavlov - TASS), Givi (Mikhail Tolstykh - TASS) and some others," he said on Rossiya-24 television, when asked about greater activity by sabotage groups in the region. "All orders have now been given. In principle, we can say that since the start of the special military operation, all security agencies have been working in the regime of heightened readiness.".
