MOSCOW (Sputnik) — According to Yonhap News Agency, South Korea's air forces spent eight days inspecting airports in Gwangju, Gimhae, Daegu, Cheongju, Sacheon and Wonju, all of which share runways with the military.
The inspection came after repeated threats from Pyongyang, the media outlet claimed.
Earlier this month, North Korean leader Kim Jong Un has vowed to attack Seoul government buildings if South Korea challenges Pyongyang.
North Korea's threats against Seoul come as the maritime portion of the annual Foal Eagle military exercises between South Korean and US forces began on Thursday. Foal Eagle is a series of joint and combined field training exercises conducted by US-South Korea Combined Forces Command each year.
As in past years, North Korea responded to the beginning of Foal Eagle with a threat to annihilate its enemies with nuclear weapons.
