North Korean nuclear test "hostile and dangerous": Trump

President Donald Trump has reacted to what he's calling "a major Nuclear Test'' by North Korea, branding the North "a rogue nation'' whose "words and actions continue to be very hostile and dangerous'' to the United States.

North Korea said it has conducted its sixth and most powerful nuclear test to date, and claiming a "perfect success.''

Trump was planning to convene his National Security Council today to consider options following the test,

Trump tweeted North Korea "has become a great threat and embarrassment to China, which is trying to help but with little success.''

China is by far the North's biggest trading partner.

French President Emmanuel Macron has condemned "in the strongest possible terms'' North Korea's nuclear test.

In a written statement, Macron "calls on the members of the United Nations Security Council to quickly react to this new violation by North Korea of international law.''

He also calls for a "united and clear reaction of the European Union.''

He says the international community "must treat this new provocation with the utmost firmness'' to bring North Korea back to the path of dialogue and give up its nuclear and missile programs.

North Korea's nuclear test Sunday was apparently its most powerful yet. State-controlled media say it was a hydrogen bomb. 

South Korea's weather agency says the detonation set off a magnitude 5.7 earthquake.

The Russian Foreign Ministry says North Korea's claim "deserves the strongest condemnation.'' 

It's calling for all parties to refrain from escalating tensions further.

The ministry issued a statement Sunday urging immediate dialogue and negotiations. It says that's the only way settle the Korean Peninsula's problems, "including the nuclear one.''

The ministry says Russia reaffirms its readiness to participate in negotiations,"including in the context of the implementation of the Russian-Chinese road map.'' 

Under that proposal, North Korea would suspend nuclear and missile tests in exchange for the U.S. and South Korea suspending their joint military exercises.

North Korea's nuclear test Sunday was apparently its most powerful yet.

The country's state-controlled media say it was a thermonuclear device and a "perfect success.''
