North Korea's foreign minister brushed aside US President Donald Trump's fiery threat to destroy his nation, comparing it to a "dog's bark" and suggesting Pyongyang would not be deterred by the rhetoric. Trump used his stormy maiden address at the United Nations General Assembly on Tuesday to warn the North that Washington would "totally destroy" it if the US or its allies were attacked. Arriving in New York for the UN meetings on Wednesday, North Korean Foreign Minister Ri Yong-ho was mobbed with questions from reporters about the Trump speech and replied with a proverb. "There is a saying that marching goes on even when dogs bark," he said as he entered his hotel. "If they are trying to shock us with the sound of a dog's bark they are clearly having a dog dream."
