A Russian frigate fired two flares at a Danish military helicopter monitoring it in international waters off Gedser on Sept. 14, one passing at close range, Reuters reported on Sept. 15, citing a Danish Armed Forces statement. On Sept. 15, Italian jets under NATO's Baltic Air Policing Mission shot down a drone entering Lithuanian airspace from Belarus near Kaunas, and, separately, train services across the Netherlands were interrupted after pipes were found deliberately fixed to tracks at some 20 sites in a suspected sabotage operation.
