The U.S. imperialist aggression forces committed more than 110 cases while the south Korean puppet army more than 70 cases, at least 180 in all.

The U.S. imperialist aggressor forces' U-2 based in south Korea was busy with photographing and electronic spying on the DPRK on Feb. 26 and 27. The number of cases of aerial espionage by this plane reached more than 20 this month.

An overseas-based RC-135 of the U.S. imperialists was also busy with aerial monitoring and photographing of the overall areas of the DPRK including its east coast on Feb. 21 and 24.

The U.S. imperialists hurled overseas-based E-3 into the joint air battle exercises frantically staged in the sky above south Korea from Feb. 4 to 11. It was busy commanding flying corps involved in the exercises and conducting aerial espionage against the DPRK.

On Feb. 24 the U.S. imperialists and warmongers of the south Korean puppet army let 17 strategic and tactical reconnaissance planes with various missions conduct intensive monitoring and electronic reconnaissance against the DPRK.

The south Korean puppets mobilized 2-3 tactical reconnaissance planes every day for spying on the frontline areas of the DPRK side.

The above-mentioned aerial espionage frantically perpetrated by them by using every possible means including spy satellites clearly indicates that their moves to invade the DPRK have reached an extremely reckless phase.
