Kremlin Spokesman Dmitry Peskov said Saturday nobody can treacherously shoot down Russian planes, Sputnik reported.

"Now, when there has been no invasion, nobody can treacherously shoot the Russian plane in its tail," Peskov told Rossiya 24 television channel.

The downing of the Russian Su-24 fighter jet by Turkey has dealt great damage to bilateral relations between Moscow and Ankara, he said.

"The Russian president said yesterday that everything about the Turkish president is a concern of Turkish voters, it is not our business. Out concern are, of course, bilateral Russian-Turkish relations that have been badly damaged."

The attack is an unprecedented challenge; Russia responded correspondingly, according to Peskov.
