Russian scientist denies helping Iran build bomb

A Russian scientist accused of helping Iran develop technology necessary to build a nuclear weapon has denied assisting its nuclear program. Vyacheslav Danilenko gave an interview to one of Russia's leading newspapers in which he said: "I am not a nuclear scientist and I am not the founder of the Iranian nuclear program."

A report this week by the UN nuclear watchdog said a "foreign expert" had assisted Iran with developing an advanced explosive device. The Washington Post identified him as Danilenko. (Associated Press)
