US President Donald Trump has shared a symbolic handshake with North Korean leader Kim Jong-un in the heavily fortified zone dividing the two Koreas.
Mr Trump became the first sitting US president to cross into North Korea after meeting Mr Kim at the demilitarised zone (DMZ).
Critics have dismissed it as pure political theatre, but others say it could set the scene for future talks.
Their last summit ended abruptly with no progress on denuclearisation talks.
With no time for the all-important backroom diplomacy, it is expected to be largely a photo opportunity. However, it will be seen as a sign of their ongoing commitment to the denuclearisation talks.
Negotiations with North Korea, to try to convince it to abandon its controversial nuclear programme, reached a peak last year when Mr Trump and Mr Kim had a historic meeting in Singapore.
They both committed to the "complete denuclearisation" of the Korean peninsula, but without clarifying what that meant.
