President-elect Donald Trump tweeted Monday evening that North Korea won't reach the final stages of developing a nuclear weapon that will be able to hit the United States.

"North Korea just stated that it is in the final stages of developing a nuclear weapon capable of reaching parts of the U.S. It won't happen!" the president-elect wrote.


North Korean leader Kim Jong Un said during his annual New Year's address on Sunday that preparations for launching an intercontinental ballistic missile have "reached the final stage."

The development came after the country claims it tested its first hydrogen bomb last year.

North Korea, which has been at odds with the United States since the start of the Korean War in 1950, first tested a nuclear weapon in 2006. A nuclear test was conducted last year on Jan. 6.
