Launch of supersonic Russian interceptor aircraft MiG-31K triggers air raid warnings across Ukraine

The sirens were likely triggered by the launch of a supersonic Russian interception aircraft, a MiG-31K, at 4:35 pm from an airfield near the Belarusian town of Machulyshchy, according to the Belarusian monitoring project Hajun.

The MiG-31K is capable of launching Kinzhal hypersonic missiles.
