U.S. general says he believes North Korea can build nuclear warhead

WASHINGTON (Reuters) - The commander of U.S. forces in South Korea said on Friday he believes Pyongyang has the capability to build a nuclear warhead that can be mounted on a ballistic missile, but added there were no tests or other evidence it has taken that step.

Army General Curtis Scaparrotti said he thought North Korea's connection with Iran and Pakistan meant it probably had access to the expertise needed to miniaturise and mount an atomic weapon on a missile.
