The International Campaign to Abolish Nuclear Weapons was honored for its work to foster a global ban on the weapons, the Norwegian Nobel Committee said.
"The global community is divided between the nuclear powers and countries that do not have nuclear weapons".
I don't denounce it as a risky diversion.
It also represented a moment of vindication for the members of the winning organization, known by its acronym ICAN, and for the United Nations diplomats who were responsible for completing the treaty negotiations.
The Nobel committee does not release names of those it considers for the prize, but said 215 individuals and 103 organisations were nominated for this year.
JOHN BURROUGHS, Lawyers Committee on Nuclear Policy: It brings much more attention, of course.
The Nobel committee praised ICAN's efforts toward securing the 2017 U.N. Treaty on the Prohibition of Nuclear Weapons. It's really going to give momentum to getting states to join the treaty.
The treaty will go into effect 90 days after 50 United Nations member states have formally ratified it.
During the treaty negotiations, Toshiki Fujimori, assistant secretary-general of Nihon Hidankyo, recounted before delegates his experience of the "hell on Earth" of the Hiroshima bombing.
Michael Douglas with ICAN Executive Director Beatrice Fihn in 2016. "I can imagine a world without nuclear weapons, and I support ICAN", the Dalai Lama declares.
"We live in a world where the risk of nuclear weapons being used is greater than it has been for a long time", she said.
A statement from his spokesman's office noted that "nuclear anxieties are at the highest level since the Cold War" and stressed "the urgency to do all we can to end the threat of a nuclear nightmare".
Trump attempts to say 'Puerto Rico' with a Spanish accent, fails spectacularly
Before the trip, Ms Cruz had begged the federal government for more aid, warning them that people on the island were dying. And he used an exaggerated Spanish accent several times while saying the territory's name.
He is also engaged in a perilous game of brinksmanship with North Korea, threatening "fire and fury" and exchanging insults with young dictator Kim Jong Un.
Berit Reiss-Andersen, chairwoman of the Norwegian Nobel Committee, told reporters that the award was not meant to send a message directly to Trump.
"It was really hard to believe it at first, so we were a little anxious it was a prank", she said. The committee instead meant to give "encouragement to all players in the field" to disarm.
In 2015, Tehran signed a deal agreeing to inspections and promising that it would use nuclear technology only for energy or other civilian purposes in exchange for the lifting of worldwide sanctions. "We can see that right now". The announcement in Oslo, Norway, cited North Korea's actions that have sparked verbal assaults from President Trump.
He expressed hope the prize will "speed up the flow of countries joining the treaty", adding that he hopes ICAN can step up its appeals to countries to join the treaty in order to "make it more effective".
The White House and leaders of other nuclear powers have instead endorsed the nuclear Non-Proliferation Treaty, which went into effect in 1970 and which limits but does not ban the powerful weapons.
"And the humans are using primal instincts of aggression and warfare and hostility, which have got to the point, because of these weapons, of being a threat not just to the enemy, but a threat to all life".
He said western MA activists were instrumental in ending the nuclear arms race of the 1980s.
"We are trying to send very strong signals to all states with nuclear arms, nuclear-armed states - North Korea, US, Russia, China, France, UK, Israel, all of them, India, Pakistan - it is unacceptable to threaten to kill civilians". Neither the United States nor any other member states of the North Atlantic Treaty Organization are among the signatories.
The Treaty on the Prohibition of Nuclear Weapons, negotiated earlier this year, opened for signature at the United Nations last month.
But on this issue, the naysayers are in the clear minority.
The United States and close allies, including France and Britain, have sought instead to strengthen the almost half-century-old Nuclear Non-Proliferation Treaty, which aims to prevent the spread of nuclear weapons but does not ban them outright.
Around 4,000 are now deployed and ready to be used, according to figures from the Federation of American Scientists.
