South Koreau has unveiled a cruise missile that could hit the office of North Korea’s leaders in a move to ramp up Seoul’s bid against its neighbor’s nuclear developments.

The Defense Ministry released video footage of the missiles being launched from destroyers and submarines and striking mock targets.

“The cruise missile being unveiled today is a precision-guided weapon that can identify and strike the window of the office of North Korea’s leadership,” ministry spokesman Kim Min-Seok told reporters.

South Korean officials declined to say the exact range of the missile but said it is capable of striking “anywhere” in North Korea, according to Reuters.

Pyongyang staged its third nuclear test Tuesday prompting the move from Seoul to address concerns that it is technologically behind the pariah state. South Korea also launched a satellite for the first time last month.

The North claimed Tuesday’s test was merely the “first response” to what it perceives as “US hostility” and warned of “second and third measures of greater intensity”.

The international community, including the North’s closest ally, China, expressed stern opposition to the provocations and called for denuclearization of the Korean peninsula amid rising stakes.
