South Korean and the US forces have started live-fire exercises to demonstrate their military capability against the North's threats.

South Korea's Defence Ministry said some 2,500 troops from both countries are taking part in the exercises, which will continue until mid-June.

Last week, North Korea's State Media reported that Leader Kim Jong Un had approved final preparations for the launch of the first Military spy satellite.

U.S. and South Korean Forces have been carrying out various training exercises in recent months, including air and sea drills, after many drills were scaled back amid hopes for diplomatic efforts and covid-19 restrictions.

North Korea has reacted angrily to the drills, which it characterises as preparation by U.S. and South Korean Forces for an invasion.
