Pentagon report says North Korea likely has nuclear tipped missiles

SEOUL/WASHINGTON (Reuters) - A Pentagon spy agency has concluded with "moderate confidence" that North Korea has developed a nuclear-tipped ballistic missile, an assessment swiftly dismissed by several U.S. officials and South Korea.

The Defense Intelligence Agency (DIA) said such a weapon would probably be unreliable. Its assessment, made public by a U.S. lawmaker in Washington, comes amid threats of war by North Korea and just hours before U.S. Secretary of State John Kerry arrives in Seoul on a visit to the region that will include stops in China and Japan.
