Iran tested advanced nuclear warhead: report
Thu Nov 5, 2009 7:25pm EST

LONDON (Reuters) - The U.N. nuclear watchdog has asked Iran to explain evidence suggesting the Islamic Republic's scientists have experimented with an advanced nuclear warhead design, the Guardian reported in its Friday edition.

The newspaper, citing what it describes as "previously unpublished documentation" from an International Atomic Energy Agency compiled dossier, said Iranian scientists may have tested high-explosive components of a "two-point implosion" device.

The IAEA said in September it has no proof Iran has or once had a covert atomic bomb program.

The Vienna-based IAEA was not immediately available for comment on Thursday.

Iran's Foreign Ministry and the Atomic Energy Organization of Iran (AEOI) were also unavailable for comment when contacted by Reuters.
