Tonight scientists doubt north koreas claim that it tested a Hydrogen Bomb, which would be far more powerful than the three atomic bombs that its tested before. Data from seismographs indicated a blast last night equal to around 7,000 tons of tnt. But thats not large by atomic bomb standards. Seth doane begins our coverage. Was how north koreas state media put it. Defending its Nuclear Arsenal as a powerful deterrent against the u. S. , which it called the cheiftain of aggression. The underground test registered as a 5. 1 magnitude quake. It was close to the site of three previous n nlear tests. The news sparked cheers in north korea and rattled nerves in south korea, which questioned whether the ex`losion was big enough to be a Hydrogen Bomb. North korea is known for its saber rattling, but possessing a Hydrogen Bomb would be a major and surprising step forward. When we were in north korea last october, it a aearedelations with china, its biggest ally, were warmingng china had sent a top official to the ceremony, but there was no hint of that today. Chinas Foreign Ministry will there be some action on chinas part . China has been using words and actions, spokeswoman chunying said, but demilitarisation requires efforts from all parties. Ultimately north korea wants to create a weapon capable of reaching the mainland united states. Regardless of what was tested, this likely from slides more research and another step toward that goal. Pelley seth doane reporting from beijing tonight. Seth, thank you. North korea also claimed that its Hydrogen Bomb was miniaturized to o t on a missile, which would be a huge engineering achievement, also unlikely. David martin is at the pentagon. Reporter u. S. Aircraft flying out of japan will collect air samples off the chest of north korea to determine exactly what kind of Nuclear Device went off. But based on analysis of the seismic wave the blast highly sceptical of the north korean claim it successfully tested a Hydrogen Bomb. Last nights explosion is estimated to have been less than 10 kilotons, about half the power of the weapon which destroyed hiroshima at the end of world war ii. A Hydrogen Bomb, which has never been used in war but was tested in the pacific during the 1950s, would be 50 to 100 times more powerful. Whatever kind of device was detonated, the greatest mystetey about north Korean Nuclear weapons is wther they have the capability to launch one against the united states. North korea has a missile capable of reaching that far, but it has never been tested. To be on the safe side, the u. S. Keeps its Missile Defense system, which Officials Say is capable of shooting down a small number of north korean missiles, on constant alert. North korea seems to spepealize in nasty surprises. U. S. Intelligence had expected happen last night. Scott . Pelley david martin reporting tonight. David, thank you. Well, worries about chinas slowing economy shook up Financial Markets again today.

Reporter texas senator ted cruz was born in canada but to an american mother, legal scholars widely agree that makes him a nach ralborn american citizen. Trump once shared that view but has apparently had a change of heart as cruz climbed to the top of some iowa polls. The billionaire now argues a cruz candidacy could imperil the g. O. P. The problem is that if the democrats bring a lawsuit, the lawsuit could take years to resolve, and how do you have a candidate where theres something, you know, over the head of the party and that individual . Reporter its familiar territory for trump, who was the figurehead for the birther movement, questioning president obamas hawaii roots. Our president has finally released a birth certificate.

After weeks of trying to reach kostenko, we drove out to cole country clinic, located at the end of this narrow twomile logging road. We came face to face with a rottttiler. Shutting down these clinics can often take years because these are licensed doctors writing legal prescriptions. Therein lies the problem.
