N Korea cancelled Pence Olympic meeting in S Korea, says US
POOL
US Vice-President Mike Pence was due to meet North Korean officials at the Winter Olympics last week, US officials have said, but the North Koreans pulled out at the last moment.
Mr Pence was in South Korea for the opening of the Winter Olympics.
A spokesman said he was scheduled to meet North Korean leader Kim Jong-un's sister, Kim Yo-jong, among others.
It would have been the first official interaction between North Korea and the Trump administration.
State Department spokeswoman Heather Nauert said when the "possibility arose" of a brief meeting with the North Korean delegation, Mr Pence "was ready to take this opportunity to drive home the necessity of North Korea abandoning its illicit ballistic missile and nuclear programs".
"At the last minute, DPRK [Democratic People's Republic of Korea] officials decided not to go forward with the meeting. We regret their failure to seize this opportunity," she said in a statement.

- N Korea leader's sister takes 'real power' south
North Korea's attendance at the Winter Olympics was seen as a major thaw in consistently tense relations on the Korean peninsula.
But there were also concerns that Pyongyang, which has been widely condemned for its repeated testing of nuclear weapons and conventional missiles, was using the event simply to improve its international image.

The US - among others - has warned against easing pressure on the North Koreans to abandon their nuclear programme and improve their human rights situation.
Mr Pence's chief of staff, Nick Ayers, said North Korea had "dangled a meeting in hopes of the vice president softening his message, which would have ceded the world stage for their propaganda during the Olympics".
"This administration will stand in the way of Kim's desire to whitewash their murderous regime with nice photo ops at the Olympics. Perhaps that's why they walked away from a meeting or perhaps they were never sincere about sitting down," he said.
On leaving the Games, Mr Pence said the US and its allies remained firmly aligned on North Korea
"There is no daylight between the United States, the Republic of Korea and Japan on the need to continue to isolate North Korea economically and diplomatically until they abandon their nuclear and ballistic missile programme."
However, South Korea's President Moon Jae-in has said he is considering accepting an invitation to visit Kim Jong-un in Pyongyang.
It would be the first summit in more than a decade between Korean leaders.

AI ripe for exploitation, experts warn
GETTY IMAGES
Drones turned into missiles, fake videos manipulating public opinion and automated hacking are just three of the threats from artificial intelligence in the wrong hands, experts have said.
The Malicious Use of Artificial Intelligence report warns that AI is ripe for exploitation by rogue states, criminals and terrorists.
Those designing AI systems need to do more to mitigate possible misuses of their technology, the authors said.
And governments must consider new laws.
The report calls for:
- Policy-makers and technical researchers to work together to understand and prepare for the malicious use of AI
- A realisation that, while AI has many positive applications, it is a dual-use technology and AI researchers and engineers should be mindful of and proactive about the potential for its misuse
- Best practices that can and should be learned from disciplines with a longer history of handling dual use risks, such as computer security
- An active expansion of the range of stakeholders engaging with, preventing and mitigating the risks of malicious use of AI
Speaking to the BBC, Shahar Avin, from Cambridge University's Centre for the Study of Existential Risk, explained that the report concentrated on areas of AI that were available now or likely to be available within five years, rather than looking to the distant future.
'Game changer'
Particularly worrying is the new area of reinforcement learning where AIs are trained to superhuman levels of intelligence without human examples or guidance.
He outlined some of the scenarios where AI could turn "rogue" in the near future:
- Technologies such as AlphaGo - an AI developed by Google's DeepMind and able to outwit human Go players - could be used by hackers to find patterns in data and new exploits in code
- A malicious individual could buy a drone and train it with facial recognition software to target a certain individual
- Bots could be automated or "fake" lifelike videos for political manipulation
- Hackers could use speech synthesis to impersonate targets
Miles Brundage, research fellow at Oxford University's Future of Humanity Institute, said: "AI will alter the landscape of risk for citizens, organisations and states - whether it's criminals training machines to hack or 'phish' at human levels of performance or privacy-eliminating surveillance, profiling and repression - the full range of impacts on security is vast.
"It is often the case that AI systems don't merely reach human levels of performance but significantly surpass it.
"It is troubling, but necessary, to consider the implications of superhuman hacking, surveillance, persuasion, and physical target identification, as well as AI capabilities that are subhuman but nevertheless much more scalable than human labour."
Dr Seán Ó hÉigeartaigh, executive director of the Centre for the Study of Existential Risk and one of the co-authors, added: "Artificial intelligence is a game changer and this report has imagined what the world could look like in the next five to 10 years.
"We live in a world that could become fraught with day-to-day hazards from the misuse of AI and we need to take ownership of the problems - because the risks are real.
"There are choices that we need to make now, and our report is a call to action for governments, institutions and individuals across the globe.
"For many decades hype outstripped fact in terms of AI and machine learning. No longer. This report looks at the practices that just don't work anymore - and suggests broad approaches that might help: for example, how to design software and hardware to make it less hackable - and what type of laws and international regulations might work in tandem with this."
The 100-page report identified three areas - digital, physical and political - in which the malicious use of AI is most likely to be exploited.
Contributors included OpenAI, a non-profit research firm, digital rights group The Electronic Frontier Foundation and the Center for a New American Security, a national security think-tank.

Trump pushes for ban on gun 'bump stocks
US President Donald Trump has signed an order to ban bump-stock devices, which were used by a gunman who killed 58 Las Vegas concert-goers last year.
Speaking at the White House, Mr Trump said he had directed the Department of Justice to propose a law to make the accessories illegal.
The Republican president said that school safety was a "top priority" for his administration.
The gun control debate has been renewed by last week's Florida school shooting.
Students and parents affected by that massacre, which left 17 dead, are planning a demonstration in the state capital of Tallahassee on Wednesday.
'We're not gonna back down'

In all around 100 students, spread across three buses, made the journey of more than seven hours to the state capital.
For many of these students, it is their first time to the capitol building in Tallahassee - much less to lobby their lawmakers over a national issue.
There is an excitement among the students, who sense that they may be on the cusp of starting a national movement.
"We're travelling to our state capital to make sure that none of these people that we grew up with - that we've known our whole lives - die in vain," Julia Salomone, 18, said confidently.
So how do the students expect the politicians to receive them? "Honestly, I feel like they're gonna be overwhelmed by us because they're going to see in our faces our determination, our commitment to this, because this is all we're fighting for right now," 16-year-old Rain Valladares said. "They're gonna look us in the face and see that we're not gonna back down."
What did Trump say?
At an event on Tuesday recognising the bravery of law enforcement, Mr Trump said he had directed Attorney General Jeff Sessions to finalise new guidelines to declare bump stocks illegal "very soon".
"The key in all of these efforts, as I said in my remarks the day after the shooting, is that we cannot merely take actions that make us feel like we are making a difference, we must actually make a difference," he said.
"We must move past clichés and tired debates, and focus on evidence-based solutions and security measures that actually work and that make it easier for men and women of law enforcement to protect our children and protect our safety."
GETTY IMAGESWhat are bump stocks?
The accessories can make semi-automatic rifles fire as rapidly as machine guns.
They can be bought for as little as $100 (£70) without the need for a criminal background check.
The device was used by a 64-year-old gambler who rained bullets on a crowd at an outdoor country music festival on the Las Vegas Strip in October last year.
More than 500 people were injured in that attack, considered America's worst ever mass-shooting by a lone gunman.
Audio analysis found the attacker, Stephen Paddock, was able to fire 90 bullets within 10 seconds from his room in the Mandalay Bay Resort and Casino.
Didn't Congress plan to ban them?
Both Democrats and Republicans agreed in the nationwide wave of horror following the Las Vegas attack that the sale of bump stocks should be outlawed.
But a bill introduced to ban bump stocks, trigger cranks and other devices that can speed up a semi-automatic rifle's rate of fire has since stalled.
In December, the Bureau of Alcohol, Tobacco, Firearms and Explosives began considering a regulation for bump stocks, opening a process that drew more than 35,000 public comments.
Proposals to ban bump stocks have been put forward with mixed results at state level, including in South Carolina, Illinois, Washington and Colorado.
Previous efforts to introduce gun control measures in the wake of mass shootings in recent years have gone nowhere in the US Congress.
Might Trump consider any other gun control?
On Tuesday, the White House signalled it was open to an age limit for people buying AR-15-type assault rifles, like the one used in last week's deadly school shooting in Parkland, Florida.
"I think that's certainly something that's on the table for us to discuss and that we expect to come up over the next couple of weeks," said White House spokeswoman Sarah Sanders, when asked about a possible age requirement. The age limit in most US states for buying an AR-15 is 18.
Over the weekend, Mr Trump said he was supportive of a bipartisan bill that seeks to improve the checks in place before someone can buy a gun.
That legislation intends to patch holes in the FBI's background check System, which processed more than 25 million gun ownership applications last year.
Failures in that database were exposed by last week's Florida high school shooting, allegedly by a 19-year-old gunman with a history of mental health issues. Bump stocks were not used in that attack.
Will this time be different?
Analysis by Anthony Zurcher, BBC News, Washington
Whether the bureaucratic review process just initiated by the president will amount to a comprehensive ban on bump stocks depends very much on how the yet-to-be-written regulation is crafted.
Still, it's the closest the Trump administration has come to new firearm regulation after multiple mass shootings - and, perhaps, a reflection of the new pressure the president is feeling on the gun issue.
Congress, of course, could have stepped in at any point in the five months since the Las Vegas massacre and banned bump stocks without this contorted bureaucratic process. The NRA, however, isn't keen on seeing a bipartisan coalition forming to enact any kind of new federal gun-control laws.
The question now is whether Mr Trump's move relieves the pressure to "do something" after Parkland. If the past is any guide, attention will fade and the drive to enact new legislation will slow. Will this time be different?
