The sister of North Korean leader Kim Jong-un has denounced the United Nations Security Council for "double standards" over weapons development and a "grave political provocation" after it convened a meeting over Pyongyang's launch of an intercontinental ballistic missile.

North Korea has test-fired a pair of long-range strategic cruise missiles, North Korean state media say, calling it a test to confirm the reliability and operability of nuclear-capable weapons.

China and Russia have voiced opposition to further sanctions by the United Nations Security Council (UNSC) against North Korea over its missile tests, as the United States urges the council to impose such measures on Pyongyang.

Former US vice president Pence has blamed the Biden administration for North Korea’s latest missile test, which has created panic in the United States.
