Kim Jong-un dares: North Korean fighters fly near border; Seoul scrambles F-35

North Korea flew fighter jets close to the South's border in another show of force. Pyongyang flagged 'reckless behaviour' & issued a warning to the South Korean military. Uptick in tensions, North Korea flew 10 fighter jets close to the inter-Korean border. North Korean jets crossed a 'reconnaissance line' which triggers an operational response. In response, Seoul scrambled fighters, including the cutting-edge F-35 stealth jet.
