Kremlin warns of 'undesirable scenario' if Ukraine uses foreign soil for combat aviation

The Kremlin on Wednesday reiterated its warning against Ukraine's combat aviation using foreign airfields, saying it is an "undesirable and potentially dangerous scenario."

"There was already an explanation from the Defense Ministry about the possibility of using (by Ukraine) some other airfields for combat aviation. This is a very undesirable and potentially dangerous scenario," Kremlin spokesman Dmitry Peskov told reporters in Moscow.

On Sunday, the Russian Defense Ministry said if any country provides airfields for Ukraine's military aviation with subsequent use against the Russian armed forces, it "may be regarded as the involvement of these states in an armed conflict."

On allegations leveled by the Russian government that Ukraine was developing biological weapons at facilities supported by the US, Peskov said: "Surely it will be interesting for the whole world to understand and find out what these institutions were doing."
