US President Donald Trump warned that North Korea's Kim Jong-Un could "void" their "special relationship" after reports of an "important" missile test.
He took to Twitter to highlight that the North Korean leader had "far too much to lose, everything actually, if he acts in a hostile way" and insisted that the nation "denuclearise as promised".
On Sunday, North Korea's state media confirmed that a "very important" test was carried out at its Sohae satellite launch site.
