North Korean leader Kim Jong-un sampled Singapore's nightlife on Monday evening ahead of his historic meeting with US President Donald Trump, taking in the views on the rooftop of the city's iconic Marina Bay Sands hotel and other sights.

In a surreal scene, one of the world's most notorious dictators was cheered by hundreds of onlookers when he entered the foyer of the hotel accompanied by dozens of suited security guards. Mr Kim appeared to be enjoying the attention, waving at the crowd before being ushered into a lift to the 57th floor.
