"It was a flight aimed to show off the military might of South Korea and US' combined air force power," South Korea’s Yonhap news agency reported, quoting a defense ministry official in Seoul.
Demanding the cessation of South Korea's propaganda broadcasts critical of its leader Kim Jong Un, North Korea declared an ultimatum, threatening to launch "strong military action" if the South does not stop its psychological warfare by 5:00 p.m. later in the day.
Tensions along the border between the two Korean states shot up after North Korea allegedly fired shells on Thursday in protest of the anti-North loudspeaker broadcasts, which the South started in retaliation for the North planting land mines on the southern side of the demilitarized zone earlier in the month.
Meanwhile, Pyongyang condemned the South’s action as an unwarranted act of aggression. Both sides accuse each other of “provocations” and threaten retaliation.
