US President Donald Trump and North Korean leader Kim Jong-un have arrived in Singapore for their historic summit.
Mr Trump flew in aboard Air Force One, a few hours after Mr Kim touched down with his entourage.
Their meeting - the first between a leader from the North and a sitting US president - will take place on Tuesday on the resort island of Sentosa.
Mr Trump described it as a "one-time shot" at peace and said the two were in "unknown territory".

The US hopes the summit will kick-start a process that eventually sees Mr Kim give up nuclear weapons.
The two leaders have had an extraordinary up-and-down relationship over the past 18 months, trading insults and threatening war before abruptly changing tack and moving towards a face-to-face meeting.
Mr Kim met Singapore's Prime Minister Lee Hsien Loong after he arrived. Mr Trump is also due to meet Prime Minister Lee before the summit begins.
