MINSK, March 7. /TASS/. Polish intelligence agents infiltrating Belarusian political opposition were involved in a subversive act against a Russian A-50 early warning and control aircraft at the Machulishchy airfield, Belta news agency reported on Tuesday citing a senior official in the Security Committee of Belarus (KGB).

"Preliminary investigative measures allow us drawing a conclusion about the involvement in the preparation of an act of terrorism of agents representing special services of the Republic of Poland, who come from the so-called fugitive Belarusians supporting the violent overthrow of the Belarusian Constitution and were actively involved in the events in August 2020," Konstantin Bychek, a deputy head of the KGB’s Investigation Department, stated.

It was reported at the end of February that the Machulishchy airfield had been attacked and the A-50 long-range radar surveillance and control aircraft of the Russian Aerospace Forces allegedly sustained significant damage.

Later, Belarusian television aired footage of the A-50 aircraft in good condition while moving on the runway and while flying. It was also reported that the plane ‘escorted’ Belarusian President Alexander Lukashenko's airliner during his return from Beijing.

Lukashenko announced earlier on Tuesday that an agent of Ukrainian special services and over 20 of his accomplices had been detained in Belarus for their involvement in the attempted sabotage attack on the A-50 aircraft at the Machulishchy airfield near Minsk.

The Belarusian leader said that the aircraft did not sustain "any significant damage, except for what they say are scratches and one hole in the fuselage." Belarus requested Russia to take the aircraft away for maintenance and send another plane, which was done.
