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.

There were unconfirmed reports at the time of the Korean firing that an Iranian team was present. Iranian military advisers regularly visit North Korea to participate in missile tests.

Intelligence estimates vary about how long it could take Teheran to produce a nuclear warhead. But defence officials monitoring the growing co-operation between North Korea and Iran believe the Iranians could be in a position to test fire a low-grade device — less than half a kiloton — within 12 months.
