Besides, according to Lysenko, within the temporarily occupied Crimea, exercises by pilots of the Northern separate seaborne fighter regiment of deck-based aviation were completed on Nytka (Thread) take-off and landing system polygon near the town of Saky.
Lysenko also pointed out the terrorists have become less active in the regions adjacent to Mariupol and Novoazovsk. According to the NSDC, this can be attributed to the current presence of the OSCE Mission in the area.
