North Korea warned Saturday that it was "not too far away" from testing a long-range missile capable of hitting the continental U.S. amid an unprecedented pace of weapons tests by the nuclear-armed nation.

"The series of recent strategic weapons tests show that we are not too far away from test-firing an intercontinental ballistic missile," the state-run Rodong Sinmun said in an editorial.

Pyongyang has unleashed a string of missile launches and tests of other advanced weaponry in recent weeks as it seeks to highlight its progress toward mastering the technology needed to mount a nuclear warhead on an intercontinental ballistic missile.
