North Korea launched two more ballistic missiles off its east coast on Monday, with the powerful sister of leader Kim Jong Un saying North Korea's use of the Pacific as a "firing range" would depend on the behaviour of U.S. forces.
The launches come just two days after North Korea fired an intercontinental ballistic missile (ICBM) into the sea off Japan's west coast, prompting the United States to hold joint air exercises with South Korea and separately with Japan on Sunday.
