US President Donald Trump on Sunday became the first sitting American leader to step foot into North Korea after he briefly entered the country before holding a bilateral meeting with Kim Jong-un at the Demilitarized Zone that divides the two Koreas. Trump first walked toward the Military Demarcation Line or MDL, which divides the truce village of Panmunjom. Then Kim showed up and approached Trump. The duo shook hands and crossed the line together into the northern side and posed for photos before walking across into South Korea. Trump told the media that it was a ‘great honour to cross that line’.
