The US National Security Adviser has accused North Korea of violating a UN Security Council resolution.
In a press roundtable, John Bolton said the country's recent missile launches were illegal.
He also called on North Korea's leader Kim Jong Un to restart denuclearization talks with countries like Japan, South Korea and the US.
“Trump has held the door open for Kim, the next step is for Kim to walk through it,” said Bolton.
