North Korea's acquisition of F-35 fighter jets will force Pyongyang to develop and test "special weapons" to destroy the new aircraft, reported Korean state media quoting a government researcher, Reuters said.
In a statement published by the official Korean Central News Agency (KCNA), a director of political research at the Institute of American Studies of the North Korean Ministry of Foreign Affairs said the South Korean authorities were "shameless and rude to speak publicly about North-South reconciliation and cooperation" while buying more US weapons.
"There is no room for doubt that the delivery of 'F-35A', which is also called an 'invisible lethal weapon', is aimed at securing military supremacy over the neighbouring countries in the region and in particular at opening a 'gate' to invading the north in an emergency on the Korean peninsula," the statement said.
"We, on our part, have no other choice but to develop and test the special armaments to completely destroy the lethal weapons reinforced in south Korea."
South Korea received the first two F-35 fighter jets in March, and more are due this year. Seoul has agreed to buy 40 of these advanced aircraft and receive the last of them in 2021.
The statement described the South's possession of F-35s as "a very dangerous act that would result in a reaction on our part."
This comes at a time when inter-Korean relations have reached a stalemate.
"Rather, the South Korean authorities should return to their senses before it is too late and dispel the false illusions that there will be a chance for inter-Korean relations to improve if they follow in the footsteps of the United States," the statement said.
