United Nations (United States) (AFP) - Washington's UN ambassador Nikki Haley said Tuesday that "something serious has to happen" following North Korea's missile test over Japan.
"It's unacceptable," Haley said. "They have violated every single UN Security Council resolution that we've had, and so I think something serious has to happen," she added, giving no specifics.
Washington and Tokyo called for an emergency UN Security Council meeting, set to convene at 2100 GMT to discuss the crisis.
The United States, along with Japan had called for an emergency security council meeting this afternoon.
"We are going to talk about what else is left to do," Haley continued, saying that "no country" should have missiles flying over a nation of 130 million people like Japan.
New sanctions on North Korea could be discussed, the US envoy said.
"I think we have a lot to talk about today. So with all of our partners, what we hope is that China and Russia continues to work with us, like they have in the past on North Korea -- but I think enough is enough," Haley declared.
US President Donald Trump earlier warned that "all options" remain on the table to handle the crisis -- implying Washington has not ruled out a military strike.
The test launch by the isolated but defiant nuclear-armed nation was seen as a major escalation and triggered an angry response from Tokyo.
North Korea defended its right to take "tough counter-measures" in response to what it calls US aggression -- despite repeated calls from Washington for it to come to the negotiating table.
"Threatening and destabilizing actions only increase the North Korean regime's isolation in the region and among all nations of the world," Trump said, in a statement released by the White House.
