North Korea may be preparing new nuclear test - report

BEIJING/SEOUL (Reuters) - North Korea, engaged for weeks in threats of war with South Korea and the United States, appears to be preparing for a fourth nuclear test, with movement at its atomic test site mirroring earlier blasts, a newspaper reported on Monday.

The report, quoting a senior South Korean government official, followed unusually harsh rebukes of North Korea by China, Pyongyang's sole diplomatic and financial ally.
