South Korea has announced a deal with the United States to more than double the range of Seoul's missile systems to cover all of North Korea.

Officials told reporters Sunday the new deal allows Seoul to extend the maximum range of ballistic missiles from the current 300 kilometers to 800 kilometers, a distance long enough to cover all of the north and parts of other countries in the region.

Washington has not commented on the announcement in Seoul.

The announcement is sure to bring an angry response from North Korea.

Pyongyang says it is developing a rocket to put a satellite into orbit. However, Seoul and the U.S. say the North's satellite program is just a disguised plan to develop long-range missiles, banned under U.N. resolutions.
