Four airspace violations in past month, says defence minister
Bulgaria's defense minister said on Sunday there had been a rise in violations of its airspace by Russian military and commercial aircraft in the past month, calling the alleged breaches a "provocations toward Bulgaria and its air forces."
Nikolay Nenchev told Bulgarian television channel Nova TV that Russian military aircraft had entered what he termed "Bulgaria's area of responsibility" in NATO airspace four times in the past month.
He said the planes had turned off their transponders – communications devices that, alongside normal radars, make it easier for an airplane to be located, especially in congested air space.
