Osaka | President Donald Trump became the first sitting US president to step foot on North Korean soil on Sunday when he shook hands with Kim Jong-un on the border of the isolated regime in a historic third meeting between the two leaders.

"It's nice to see you again," Mr Kim said as Mr Trump stepped across the border while the world's media looked on. The two leaders shook hands and posed for photographers before stepping back into the demilitarised zone separating North and South Korea.
