"There's a lot of Russian airborne activity above the Gulf of Finland, especially between Kaliningrad and the Russian mainland," military spokesman Marko Luotonabilities," Britain's military said in a statement. "The motivation behind any Russian military activity is a matter for the Russian government."
Last year, Russia apologized for violations of Finnish airspace, following about a dozen such incidents over a period of two years.
Similar complaints of air violations have been made by Finland's southern neighbors, Estonia and the other Baltic states. In October 2005, a Russian fighter jet crashed in Lithuania.
