Pakistan today condemned the latest atomic explosion by North Korea as violation of UN Security Council resolutions and called on "all parties" to work for a nuclear weapons free Korean peninsula. "Pakistan condemns the nuclear test conducted by the Democratic People's Republic of Korea today, which constitutes a violation of the United Nation Security Council Resolutions and is against the objective of a nuclear weapons free Korean peninsula," the Foreign Office said, using the official name of the North. Pakistan called upon North Korea to comply with all the relevant UN Security Council Resolutions and refrain from actions which undermine peace and stability in the region. "We urge all parties to work towards the establishment of nuclear weapons free Korean peninsula within the framework of the Six-Party talks," it said. The North's state-run television reported that the country has "successfully" conducted a nuclear warhead explosion - its fifth and more powerful than it has earlier conducted - after monitors detected a 5.3-magnitude "artificial earthquake" near its main nuclear site this morning.
