U.S. warns N Korea of "massive military response"

"The two leaders agreed to stick to the goal of denuclearisation on the Korean Peninsula and keep close communication and coordination to deal with the new situation", Xinhua said in a brief dispatch.

North Korea just tested their most powerful nuclear bomb yet and caused an natural disaster 10 times more powerful than their last test.

North Korean state television was nearly jubilant in announcing what the regime calls a successful test of a hydrogen bomb. At the time of Mattis' speaking, the USA does not have an increased naval or military presence in the region, though the United States and South Korea did just complete a joint war-gaming exercise.

"Enough is enough", Haley said before the UN Security Council, according to NPR.

Hertling said that means the U.S. doesn't need to do anything drastic to counter the current North Korean threat.

The South Korean military said its missile drill had "accurately hit designated targets in the East Sea", the country's Joint Chiefs of Staff said in a statement. China strongly objects to the, saying its powerful radar can probe deep into its territory, undermining its security.

Mattis, who did not take questions from reporters, said he had attended a "small group" of national security meeting with Trump and others. The first hydrogen bomb tested by the United States in November 1952 released the equivalent energy of 10,000 kilotons (or 10 megatons) of TNT.

Thirteen oil refineries have been shut down or are in the process of closing, while several others are operating at reduced rates. Half of the 26 refineries that supply Colonial's 5,500 miles of pipeline are located between Houston and Lake Charles, Louisiana.

"We've already started with sanctions against North Korea, and I'm going to draft a sanctions package to send to the president for his strong consideration, that anybody that wants to do trade or business with them would be prevented from doing trade or business with us", Treasury Secretary Stephen Mnuchin said on Fox News Sunday.

"North Korea is a rogue nation which has become a great threat and embarrassment to China, which is trying to help but with little success", he said.

The statement questioned the growing worldwide call for more sanctions, noting that sanctions so far had "not led to any positive outcome". North Korea has made similar, unsubstantiated claims after some of its previous tests.

"It is a cruel and evil dictatorship, he starves his own people", Mr Turnbull said.

But other world leaders talked up diplomatic options on Sunday.

North Korea relies on China for approximately 90 percent of its foreign trade, and US-China trade was estimated to be worth about $650 billion a year ago. "The president wanted to be briefed on each one of them", the US Defence Secretary said. According to several media reports, the North Koreans may now have the capability to fit such a missile with a device similar to the one tested Sunday.
