In this Wednesday, May 27, 2009, photo, a giant North Korean flag flutters on the top of a 160-meter (533-foot) tower in North Korea as it is pictured from the demilitarized zone (DMZ) near the border village of Panmunjom that separates the two Koreas since the Korean War, in Paju, South Korea. North Korea on Thursday, May, 25, 2017, accused South Korea of recently firing 450 rounds from machine guns at a flock of birds at the rivals border, dismissing as a fabrication Seoul's claim that it fired warning shots at an object flying from the North.
