North Korea defies global outcry

North Korea has restarted its main nuclear plant and test-fired another short range missile, according to South Korean media, despite international condemnation over its underground nuclear detonation on Monday.Pyongyang's latest moves come as the five permanent members of the UN Security Council, together with Japan and South Korea, held an emergency session on Tuesday, but diplomats said it needed "some time" to finalise a response.South Korean paper Chosun Ilboreported on Wednesday that US spy satellites had detected steam coming from a reprocessing facility at the North's Yongbyon nuclear plant.The reported activity indicates it may have made good on a threat issued in April to restart a facility that extracts weapons-grade plutonium, although South Korea's defence ministry and National Intelligence Service said they could not confirm the report.Separately, South Korea's Yonhap news agency, quoting an official at Seoul's presidential office, said the North fired a short-range ground-to-ship missile into the Sea of Japan, also known as the East Sea, from the east coast city of Hamhung at around 9pm (12:00 GMT) on Tuesday.
