In South Korea, protesters turned out in the capital Wednesday to denounce the test and call for greater sanctions on the already impoverished North.
SOUNDBITE) (Korean) ANTI-NORTH KOREA PROTESTER CHOO SEON-HEE SAYING:
"The South Korean government and international society must punish North Korea strongly. A tough punishment is the only way to break the North."
Even China, the North's only regionally ally, expressed concern over the underground test.
This professor of international relations said North Korea's actions have only isolated the nation further and made it difficult for China, who opposes the country's nuclear testing, to support its ally.
