UN Security Council members on Tuesday discussed fresh "strong" measures against North Korea for testing a nuclear device in defiance of international constraints, Japan's UN ambassador said. The new measures will add to the set of sanctions already imposed on North Korea in 2006 for its first nuclear test, said Ambassador Yukio Takasu following a first round of discussion by the 15-nation council during a closed-door session. "What we discussed today are the content of a strong message based on what we have in Security Council resolution 1718 in 2006," Takasu said. "Nobody said that what we have done so far, what we have agreed, has been enough. We need additional measures," he was quoted as saying by DPA. Takasu said that North Korea's nuclear test on Monday was a "clear, direct threat against Japan's security and also a challenge to the Security Council."
