Foreign ministers from G-8 nations are condemning in the "strongest possible terms" North Korea's aggressive rhetoric and development of nuclear missile programs.
North Korea on Thursday claimed it had "powerful striking means" on standby for a missile launch.
In a communique approved following a meeting in London, the G-8 foreign ministers said that recent missile tests "seriously undermine" regional stability and threaten international security.
The ministers also said Pyongyang's aggressive rhetoric will only isolate North Korea, and urged the government to engage in "credible" talks on abandoning all existing nuclear and ballistic missile programs.
They urged North Korea to refrain from "further provocative acts" and expressed concern about its plans to re-open its Yongbyon nuclear facility.
