We are disappointed at the way our military reacted to the shootings on Monday by North Korean guards at a fellow soldier who defected to South Korea through the Joint Security Area (JSA) in Panmunjom.
He suffered a gunshot wound and is now recovering in a South Korean hospital, the military said.
The demilitarized zone between the two countries splits the Korean Peninsula from east to west, and is fortified with landmines, fences and guard posts.
The defector, dressed in a combat uniform, was unarmed, Al Jazeera reported.
Two American soldiers also were killed in the DMZ by ax-wielding North Korean soldiers in a 1976 brawl over an attempt to trim a poplar tree.
Seo said the North Korean soldier appears to have been shot in five places, adding that he had his first operation on Monday. They stand only several yards away from tall South Korean soldiers wearing aviator sunglasses and standing motionless like statues.
DiMaggio has held secret backchannel talks with North Korean officials four times over the past year, The Daily Telegraph reports, and has been a negotiator between the United States and North Korea for more than 20 years.
"What the president is trying to do right now is recognize that the gravest threat that America faces is North Korea developing nuclear weapons".
Panmunjomis where an armistice was signed to pause the Korean War. American presidents often visit Panmunjom and other DMZ areas during their trips to South Korea to reaffirm their security commitment to the South. Trump planned to visit the DMZ to underscore his stance against North Korea's nuclear program when he came to South Korea last week as part of an Asian tour, but his plans were thwarted by heavy fog that prevented his helicopter from landing at the border area.
"He believes that after years of investigations, of tens of millions of taxpayer dollars, there is zero evidence of any ballot being impacted by Russian interference", Short said in an interview on NBC.
Although there have been a handful of defections across the DMZ in recent years, escapes through the tense Joint Security Area are rare.
