North Korea Foreign Minister Ri Yong-ho says Trump has 'declared war' on his country

"Trump claimed our leadership would not be around much longer," North Korean Foreign Minister Ri Yong-ho told reporters outside his hotel in New York. "He declared a war on our country."

"All the member states and the whole world should clearly remember it was the United States that first declared war on our country," Ri said.

"Since the United States declared war on our country, we will have every right to take counter-measures including the right to shoot down US strategic bombers even when they are not yet inside the airspace border of country," he said.

"The question of who will be around much longer will be answered then."
