White House Casts Doubt That North Korea Tested Hydrogen Bomb

The Obama administration said that initial analysis by the U.S. is "not consistent with" claims by North Korea that it successfully tested a hydrogen bomb. Reports of a test unnerved global investors Wednesday and helped send U.S. stocks lower. White House press secretary Josh Earnest told reporters the U.S. is learning more about the reported test and that any nuclear test would break U.N. Security Council resolutions.
