North Korea says its leader Kim Jong Un has attended a test firing of newly developed precision-guided missiles.
The state-run Korean Central News Agency said on Friday that Kim ordered the firing on Thursday.
A spokesperson of South Korea's defense ministry said Kim probably attended the launch of 3 projectiles in the eastern city of Wonsan.
The spokesperson said the North is trying to upgrade its new large-caliber rockets.
In March, the North launched a new type of rocket that flew about 150 kilometers. The projectiles fired on Thursday are believed to have traveled 190 kilometers.
The spokesperson said North Korea is gradually extending the range of its missiles.
A missile with a 190-kilometer range could reach South Korea's capital Seoul and central parts of the country.
The new missiles are feared to pose a significant threat to the South Korean military and US forces stationed in the country due to difficulty in detecting their firing and intercepting them.
