Iran has arrested some of those responsible for assassinations of its nuclear scientists, state media reported on Sunday, in a continued hunt for those it says are working to sabotage its nuclear program.
Intelligence minister Heydar Moslehi said Iran had shut down two networks inside and outside the country he said were involved in training the killers, Fars
news agency reported.At least four scientists associated with Iran's disputed nuclear works have been slain since 2010 and a fifth - Fereydoun Abbasi Davani, now the head of Iran's Atomic Energy Organization - was wounded.
The West believes Iran is stockpiling enriched uranium as potential fuel for nuclear weapons and trying to develop technology needed for a workable bomb. Iran denies this, saying its nuclear activity is solely for peaceful energy purposes.
