Pentagon 'looking into reports of a possible seismic event near North Korean nuclear facilities'

WASHINGTON- The U.S. Defense Department is"looking into reports of a possible seismic event near North Korea's nuclear facilities," a U.S. official said on Tuesday.

South Korea's meteorological agency said earlier that North Korea is "likely" to have conducted a nuclear test that caused an earthquake near a known testing site in the isolated country. "We are looking into the reports of a possible seismic event near North Korean nuclear facilities," said a U.S. official, who spoke on condition of anonymity.
