North Korea starts new rockets on Monday. The rockets fly 900 kilometers. They land in the sea. Experts call them ballistische Raketen. This means long-range weapons.
South Korea and Japan see the rockets. Kim Jong-un tests many weapons. He wants to show power. The world says no to these tests.
The situation is difficult now. An explosion happens at the border. 3 soldiers from South Korea are hurt. South Korea also tests a new Hyperschall-Rakete. This is a very fast weapon.
North Korea and South Korea have no peace. They only have a Waffen-Stillstand since 1953. This means they stop fighting, but keep no peace. Both countries test many weapons. People feel great fear.
