North Korea Nuclear Test Gears Up

Here we go again:

SEOUL (Reuters) - There is increased activity at North Korea's known nuclear test site, a South Korean news report said on Thursday, suggesting Pyongyang is gearing up for a new test as it has threatened in response to tightened U.N. sanctions.

Impoverished North Korea, whose only nuclear test in October 2006 led to U.N. financial and trade sanctions, could be ready to test another nuclear device in a matter of weeks, experts have said.

"Underground nuclear tests are hard to predict and you can't tell when exactly a nuclear test would be possible, but we think the North is ready to conduct a test in a near future if it wants to," the Chosun Ilbo daily quoted a government source as saying.
