U.S. Defence Secretary James Mattis says war with North Korea would be 'catastrophic.'
Appearing on CBS' Face the Nation, Mattis said a conflict in North Korea would be the 'worst kind of fighting in most people's lifetimes.'
North Korean leader Kim Jong Un supervised the test of a new anti-aircraft weapon system and ordered its mass production and deployment throughout the country, the state news agency reported on Sunday, after weeks of defiant ballistic missile tests.
The North's KCNA news agency did not report the exact nature of the weapon or the time of the test but said it was organized by the Academy of National Defence Science, a blacklisted agency that is believed to be developing missiles and nuclear weapons.
The North has been pushing to develop a wide range of weapon systems since early last year at an unprecedented pace including a long-range missile capable of striking the mainland United States and has in recent weeks tested its intermediate-range ballistic missile, making some technical advances.
The reclusive state rejects U.N. and unilateral sanctions by other states against its weapons programme as an infringement of its right to self defense and says the program is necessary to counter U.S. aggression.
