The U.S. imperialist aggressor forces committed more than 110 cases of aerial espionage and the south Korean puppet forces at least 80 cases, bringing the total number of cases to more than 190.

They let U-2, RC-7B, RC-12, RC-800, RF-4C and E-3 fly everyday for frantic aerial espionage against the DPRK from March 9 to 20.

At least 20 cases of aerial espionage were perpetrated by U-2 of the U.S. imperialist aggressor forces present in south Korea.

RC-135 of the U.S. imperialist aggressor forces made shuttle flights from the air over waters off Musudan, North Hamgyong Province, to the air over waters east of Wonsan on March 13, 17 and 22 to perpetrate aerial observation, photographing and electronic espionage against strategic targets in the DPRK.

The U.S. imperialists perpetrated the above-said aerial espionage after deploying even "intercepting" means in the East Sea of Korea, describing the DPRK's projected satellite launch as "a missile launch." This is a wanton infringement upon the sovereignty of the DPRK and another dangerous military provocation to it.

The U.S. imperialist warmongers had better bear in mind that RC-135 and all other spy planes perpetrating espionage against the DPRK are within the range of its strikes.
