North Korea test-fired several missiles into the sea off the country's west coast Friday, sources here said.

The test, believed to be of Russian Styx missiles, comes one day after the communist nation threw out all South Korean government officials from the inter-Korean industrial complex in the North in apparent disgruntlement over the Lee Myung-bak government's hard-line North Korea policy.

The sources, speaking on condition of anonymity, said the missiles were fired at approximately 10:30 a.m. The number of missiles fired or their types could not be immediately confirmed.
