Iran has executed an Iranian man accused of killing Iranian nuclear scientist, Masoud Ali Mohammadi. Mohammadi was killed in 2010 when a bomb attached to a motorcycle outside his Tehran home was detonated.
Majid Jamali Fashi was accused of being a spy for Israel, and was hung today for his part in killing Mohammadi. Mohammadi is one of several Iranian nuclear scientists to be killed in the last few years.
Anchor Lisa Mullins talks with Kasra Naji, of the BBC's Persian service, about the case. According to Naji, Iranian television broadcast what it said was a confession made by Majid Jamali Fashi, in which he said he had been working for Israel.
Nothing is known about the circumstances under which the confession was made. Naji says no evidence has been made public for the conviction, other than the confession.
