Experts doubt test North Korea

US experts doubt that the underground nuclear test which North Korea have held concerns a hydrogen bomb.

According to scientists at Columbia University in New York Wednesday seismic effects were measured in the vicinity of the northeastern Chinese city of Mudanjiang. Its strength was 5.1 similar to Korean nuclear tests in 2006, 2009 and 2013. The test showed scientists at the equivalent of 3.5 kilotons of TNT and that is not enough for a hydrogen bomb.
Or not so-called H-bomb, the government in Washington dubbed the trial anyway as a provocation. The White House announced that it would enter into consultations with China, which maintains the only country with a reasonable relations regime in North Korea.
