Axis of Evil Update. By Con Coughlin in [1] The Telegraph, with thanks to Jeffrey Imm:

North Korea is helping Iran to prepare an underground nuclear test similar to the one Pyongyang carried out last year.

Under the terms of a new understanding between the two countries, the North Koreans have agreed to share all the data and information they received from their successful test last October with Teheran's nuclear scientists....

A senior European defence official told The Daily Telegraph that North Korea had invited a team of Iranian nuclear scientists to study the results of last October's underground test to assist Teheran's preparations to conduct its own — possibly by the end of this year.
