Israel's defense minister says intelligence agencies are familiar with a drawing said to be based on information from inside an Iranian military site showing an explosives containment chamber of the type needed for nuclear arms-related tests.
U.N. inspectors suspect Tehran has conducted nuclear arms-related tests at the site. Iran denies such testing and has neither confirmed nor denied the existence of such a chamber.
Defense Minister Ehud Barak told Army Radio on Monday that "this diagram is part of the information known to all leading intelligence agencies in the free world for some time."
Barak says the image reaffirms the need to halt Iran's nuclear capabilities.
The image was provided to The Associated Press in Vienna by an official of a country tracking Iran's nuclear program.
