North Korea's supreme military command on Thursday (March 21) warned of a "precision attack" on U.S. bases in Guam and Okinawa.

"The United States should not forget that our precision target tools have within their range the Anderson Air Force base on Guam where the B-52 takes off, as well as the Japanese mainland where nuclear powered submarines are deployed and the navy bases on Okinawa," the North's state-run television KRT newsreader said, quoting the military command spokesman.

The threat was in response to reports that the U.S. had flown nuclear-capable B-52 bombers over the Korean peninsula as part of the annual military drills with South Korean forces.

North Korea had earlier threatened a nuclear attack on the United States, something that is well beyond its current military capability.

Tensions on the peninsula have been fraught since the U.N. tightened its sanctions against North Korea following its successful third nuclear test.
