South Korea has identified a site for a high-tech U.S. missile interceptor unit, defying complaints by China and Russia. North Korea has threatened to attack the site.

FOX's Alastair Wanklyn reports from the Asia Bureau:

South Korea saying an anti-aircraft missile base in the south of the country is where these rockets will be based by the end of next year.

China today saying the move would, quote, "grossly undermine" regional security.

The site is well placed to intercept missiles aimed at U.S. bases at Osan and Pyeongtaek or the U.S. naval base in the Korean city of Chinhae.

Some local residents today protesting the plan. North Korea has said it will attack the site, although it's likely out of range of Pyongyang's short-range missiles.
