Russia's FSB chief says no doubt NATO was involved in alleged Russian drones incidents over EU, RIA reports

Russia's Federal Security Service chief said on Thursday that Moscow has no doubt about NATO's security services' involvement in incidents with alleged Russian drones over EU territory, RIA cited him as saying.
