SEOUL, South Korea — North Korea's top governing body warned Thursday that the regime will conduct its third nuclear test in defiance of U.N. punishment, and made clear that its long-range rockets are designed to carry not only satellites but also warheads aimed at striking the United States.

The National Defense Commission, headed by the country's young leader, Kim Jong Un, denounced Tuesday's U.N. Security Council resolution condemning North Korea's long-range rocket launch in December as a banned missile activity and expanding sanctions against the regime. The commission reaffirmed in its declaration that the launch was a peaceful bid to send a satellite into space, but also clearly indicated the country's rocket launches have a military purpose: to strike and attack the United States.

While experts say North Korea doesn't have the capability to hit the U.S. with its missiles, recent tests and rhetoric indicate the country is feverishly working toward that goal.
