North Korea carries out further missile test
North Korea is continuing to defy international condemnation by test-firing another missile last night.
The South Korean media says US spy satellites have also detected signs that the isolated communist state has restarted its nuclear plant in Yongbyon.
The Stalinist country has conducted a series of missile tests in the past two days after carrying out an underground test on a nuclear bomb on Monday.
The increase in such activity follows the UN's decision to condemn a rocket launch by North Korea earlier this month.
Pyongyang says the rocket was designed to send a satellite into orbit, but the US and Japan say it was really a cover for a long-range missile test.
North Korea had shut down its Yongbyon nuclear plant and its nuclear weapons programme last year as part of a deal reached in international talks.
