"The attache was given a document which includes a protest against illegal restrictions introduced by the Ukrainian side on the use of airspace over the Black Sea during December 1-2 missile firing drills to the west of the Crimean peninsula coastline," the ministry's statement read.
Earlier on Friday, Russia's Federal Agency for Air Transport (Rosaviatsiya) said Ukraine had decided to hold missile firing exercises in Russia's airspace near Crimea.
The statement noted that "Ukraine-declared south-eastern boundaries of the danger zone violate the territorial waters of the Russian Federation, which is a breach of international law and Russian legislation."
