NORTH KOREA is 'very close' to being able to attack any target in the US with thermonuclear weapons, according to a shock warning from a former US ambassador to the UN.
On Sunday, Nato Secretary General Jens Stoltenberg said: “Nato is able to respond to any attack, including ballistic and nuclear attacks.”
The second day of US military drills took place from South Korea on Tuesday, with 230 aircraft taking part in the operation called Vigilant Ace.
The Korean Central News Agency responded saying the US and South Korea “will pay dearly for their provocations”.
It added the US is "begging for nuclear war by staging an extremely dangerous nuclear gamble on the Korean peninsula”.
