A Washington-based nongovernmental organization has says Iran apparently had the help of a Russian scientist in developing a detonator and high explosives for its nuclear program.
In a report released on November 13, the Institute for Science and International Security (ISIS) identified the Russian scientist as being 76-year-old Vyacheslav Danilenko.
The ISIS report said Danilenko worked at Iran's Sharif University.
The ISIS based its conclusion on the findings of a report issued last week by the UN nuclear watchdog, the International Atomic Energy Agency (IAEA).
The UN report said there were "strong indications" that Iran's development of technologies related to its nuclear program was "assisted by the work of a foreign expert," but did not name him.
The Washington Post last week also identified Danilenko as being the unnamed foreign expert mentioned in the IAEA report.
Danilenko has denied the accusations.
