North Korea has warned that a "reckless" joint military drill by the US and South Korea could spark a nuclear war.
United Nations Security Council ministers will meet on 15 December to discuss North Korea's nuclear and missiles programs and the body will also meet separately in December to discuss human rights abuses in the North Asian country, an annual meeting that its ally China has tried to prevent for the past three years.
The launch was a message of defiance to President Donald Trump's administration, which a week earlier had restored North Korea to a US list of terror sponsors.
It flew 600 miles (950 km) before splashing down in waters near Japan and is potentially capable of striking targets as far as 8,100 (13,000 km), which would put Washington within reach.
North Korean monitoring group 38 North said the tremors could be an indication of "Tired Mountain Syndrome" - a condition where rock becomes increasingly permeable following a below-ground nuclear blast.
Graham expressed confidence in the Trump administration's ability to manage the growing conflict with North Korea.
Brian Cashman: Joe Girardi's successor either Aaron Boone, Hensley Meulens
The average age of Girardi's first seven Yankees rosters was always between 29.3 and 31.8 years, according to Baseball Reference. He spent most of his 12-year Major League Baseball career with the Cincinnati Reds .
The initial analysis shows Tuesday's launch likely involved a two-stage missile with a non-explosive dummy warhead, the official said.
"It is an open, all-out provocation against the DPRK, which may lead to a nuclear war any moment", it said in an editorial Sunday, using the North's official name.
"The stealth fighters which the enemies boast so much of will not escape the fate of a tiger moth", the North Korean commentary said.
A USA official said Saturday technical analysis of that missile's flight is ongoing but the "the North Koreans had problems with re-entry". North Korea's latest missile is believed by experts to be capable of reaching all parts of the continental U.S. Despite its range, though, reports say U.S. officials now believe the missile likely did not survive re-entry into the Earth's atmosphere.
A solid-fuel system for an ICBM would be a significant development and could allow the North Koreans to transport and launch a missile more quickly, compared to a liquid-fuel system that requires lengthy preparation. "But what we want to do is convince others, it is in their interest to do more", McMaster said.
