A top North Korean official says his country has a stockpile of nuclear weapons and is making more.

Vice Foreign Minister Kim Gye Gwan told U.S.-based ABC News Wednesday that North Korea has enough nuclear bombs to defend against a U.S. attack. But he added Pyongyang has no intention of attacking the United States.

When asked if North Korea has a missile capable of hitting the United States, Mr. Kim would not answer, saying one cannot speculate about that because the nuclear program is not aimed at the United States.

South Korean president Roh Moo-hyun is on his way to Washington for talks Friday with President Bush. The two men are expected to discuss recent signs North Korea may be willing to return to six-nation talks on ending its nuclear weapons program.
