North Korea: Kim Jong Un oversees test of "super-large" rocket launchers. The action was probably intended as a signal to US Secretary of State Antony Blinken, who was visiting Seoul at the same time.
The armed forces of South Korea and the United States had held large-scale joint military exercises for 10 days until last Thursday. Observers fear that the North could use this as an opportunity for further and larger demonstrations of military force. There will be elections this year in both the USA and South Korea.
