N Korea won't abandon nuclear weapons: Kim Jong-un's sister to US

Kim Yo Jong, sister of North Korea's leader Kim Jong-un, warned US that North Korea will not abandon its nuclear weapons development. Responding to US-led trilateral talks, she said, "'Denuclearisation' of us is nothing but a daydream that never came true." She added weapons can "never be reversed by any physical strength" and disarmament calls are "the most hostile act".
