According to the press release, NATO fighter-jets were scrambled to identify and escort one Tu-134 and one Su-27 military aircraft of the Russian Federation flying from Kaliningrad to mainland Russia in international airspace over the Baltic Sea. The Tu-134 had its onboard transponder on, a pre-filed flight plan, and kept radio contact with regional air traffic control centre. The Su-27 complied with none of those requirements.

NATO's Baltic air-policing mission is conducted from Lithuania and Estonia.
