North Korea's leader Kim Jong Un called for his country to expand production of "weapon-grade nuclear materials" and build more powerful weapons, state media reported Tuesday.
North Korea could test-fire intercontinental ballistic missiles at a normal angle and conduct its seventh nuclear test this year to perfect its nuclear and missile capabilities, South Korean lawmakers said on Wednesday, citing intelligence officials.
