US President Donald Trump has written a letter to North Korean leader Kim Jong-un saying their planned summit in Singapore next month is cancelled.
In the letter, Mr Trump wrote he felt it was "inappropriate, at this time, to have this long-planned meeting".
"Therefore, please let this letter serve to represent that the Singapore summit, for the good of both parties, but to the detriment of the world, will not take place," the letter read.
"You talk about your nuclear capabilities, but ours are so massive and powerful that I pray to God they will never have to be used."
More to come.
